3BH on Thanos, or Strange?

Looking at your roster, I'd say you probably don't need Strang3 as much as you need Thanos. I use Court Death to blast through easy nodes in story, then switch away from thanos teams. I used my Strang3 with Okoye more when he was max-champed, but my baby champ dupe isn't as fast as my 293 Medusa on most nodes. 

If you are seeing 3* opponents, Strang3 remains a problem in PVP i think. If you're primarily seeing 4*s and boosted 4*s, Strang3 is too squishy in my experience. A number of characters can 1-shot him no problem at that tier. When he launched, he was a psychological deterrent, but once you know his number, you might find you're actually seeking him out as a soft target.

Once you have a usable Okoye (I'm not sure OP's 1/0/1 counts as that), 3* Thanos is actually superior for fast clears since his Court Death benefits from Wakanda Forever. the Stun Thano5 brings to the table prevents the bonus damage. though that might be different on a champed Thano5, mine is 5/0/2 lvl 345. both benefit from strikes though, so maybe Thano5 + 4ocket is faster than Thano3 + Okoye? hard to say given my roster

I guess your 3*/5* mileage is totally going to vary on both Thano5 and 5trange. My 5* Court Death is doing 6091:1510 at 5 covers lvl 345, and my lvl 182 3* thanos is doing 4227:1083, which isn't appreciably better.

I definitely use Thanos more than Strange, but for me, it was more important to have Strange at a higher level because of his usage. I say "was" because I have both max champed now, but let me explain:

I use Thanos, like everyone else, to power though the easy nodes in PvE and the 3* nodes in DDQ. But what I found is that Thanos's Court Death, especially when paired with Rocket & Gamora (who I see you have champed), wiped the enemy team no problem even without having Thanos at max level. Increasing Thanos's level just increased the amount of self-harm every time it fired.

On the other hand, while I tend to use Strange less frequently and more situationally, those situations involve a) when he's boosted, or b) when I need to hit tile spammers for max damage as quickly as possible. Strange isn't going to down an enemy with one blast at any level but over multiple blasts that extra damage can add up and can spell the difference between finishing off a goon or eating 5K+ damage from a goon with 100 health left. And the extra healing he gives, while not significant, is a bonus.

One of my go-to teams in PvE against tile spammers is Strange + Valkyrie + a strategic third. Use supports to make your strongest color match your strongest power, then watch as the goons kindly fill up your AP. Some examples:

w 4* Luke Cage, yellow as strongest color for Luke's Hero for Hire (my go-to team vs Mindless Ones)
w 4* Rocket, blue as strongest color for Strange's Crimson Bands or Rocket's Pack
w 4* ME Hulk, purple as strongest color, Gamma Powerbomb

I know it is an older conversation but I end up using 3* Strange more than 3* Thanos.  Strange is really good against goons and his blue stun power is still a really good power even for a 3* and I still use him at times in PvE with my 5* roster since I don't have 5* Strange fully built.  I never use any of Thanos active powers and I avoid his Court Death because I find that it never really helped that much in speed for the damage cost to his allies for me.  I suppose if you are an ultra competitive player those few extra seconds from Thanos are worth it but I generally find it was not worthwhile for me so Thanos usually just sits on the shelf.

You don't need to be ultra competitive, just competitive. Thanos shaves significant time off PvE clears, even if it's the 3-star version. You're deluding yourself if you think it's only seconds you're losing by not using him. It's minutes.

Consider the amount of matches and time it takes just to clear the three easy nodes four times. That's twelve total fights and thirty-six total opponents.

Using three 5-stars who down one opponent per match-3:
36 match-3s and about 9 minutes

Using R&G + Guardian/Kitty and Medusa downs 3 opponents per two match-3s:
24 match-3s and about 6 minutes

Using any of the above with Thanos downs 3 opponents in one match-3:
12 match-3s and about 3 minutes 

I should clarify I guess, I never said he wasn't faster than Strange, my opinion just let useful for my roster. I still use 3* Strange in situations but never use 3* Thanos (unless required).  Thanos does provide several seconds per node clear benefit from 3* Thanos, yes I agree it adds up to many minutes overall in overall clears. It also depends on SCL etc, he is certainly more valuable at lower SCL's (3* version).  I don't have 5* covered/leveled enough to comment on him but if you want to place high in higher SCLs you usually need him too. If the team damage is worth that time and possible healthpacks then he should be used, for my roster I never found him useful as I never attempted to get T25 placement. Although I almost always get between 25-50 in any SCL I decide to play in without playing optimally or competitive.

Given how much of playing an Easy match is outside the actual match itself, it's not going to be a linear improvement. Still an improvement, but I'd guess something more in the ratio of 9:7.5:6 or so.
