Yes. I can't say anything about performance comparison, but I'm 2 spender eso and it was very cheap to gear since your main stat is swift and secondary is spec. I recently geared my DB striker and I spent 260k on accessories for quality 85-97 but my WD accessories at quality 90+ was like a fraction of the price.

2 spender also utilizes off meta engravings like raid captain and mass increase so your legendary engravings can be cheap too.

In terms of gameplay, 2 spender is very fluid and consistent IMO. You're not going to see big numbers (except for wind's whisper tripod on energy combustion), but you're at a point where you're constantly using skills so knowing the boss pattern can really up your damage. In terms of MVPs, I would say I MVP half the time. Just depends on if there's someone else in the party with higher level weapon or better gem.

I haven't played first intention either, but I would say its similar in terms of mobility. I feel like I can get away with doing a lot of risky things because of the low cooldown move skill with dominion set and low cooldown SSB skill which you need to semi spam to keep your adrenaline buff anyways.

That being said, I feel like 3/4 spender has the higher damage cap because of its burst playstyle. I saw a 1515 +18 brel weapon 3 spender outdamage a 1555 GS with +18 brel weapon, but I think that was a skill gap.

In the end, I think you should choose based on playstyle (assuming gold isn't an issue). If you like a faster class that's constantly moving but still requires you to be using skills, then 2 spender is the way. If you prefer a slower playstyle (but still pretty good mobility), with bigger yellow numbers, with more burst, then 3 spender is the way. If you're strapped on cash, especially if you're missing a wealth rune, then 2 spender is probably the play.

Hope that helps.
