Both are solid choices, you won’t be upset either way, I was 50/50 on both but decided to do the v2 for 350x350 print area. I have an enclosed mk3s that I use as well, I was putting together a buildtak surface (which I swear by for abs and nylon) for my mk3s and snapped this photo to compare print area size. I still want to do a trident (and maybe convert my mk3s to a switchwire) but I’d build it to match the MK3s wrt bed size and I’d totally consider a bowden extruder.

All that said, it is markedly faster than the mk3s and I’m definitely no where near pushing it to its limits. There’s a lot to build but I would call it difficult, racking the gantry and belt tensioning being the parts I spent the longest time on. I limit to 24 mm^3/s even though I could go faster, it still just absolutely flies with something like a 0.8mm nozzle. My only other headsup is that modding it is addicting, I’ve thrown on titanium backers and a kinematic mount for the bed, have a whole bunch of other ones in the pipe as well.
