I believe that the MAP ECU 1 and 2 behave exactly the same when it comes to fueling adjustments, its just that the 2 adds many other features like timing and boost control, 2 maps, launch control, etc. The 1 only controls fuel and that is it.

Are you NA-T or TT swap? From what I'm told, the NA-T is difficult to convert to MAP because of the AF meter it has from the factory, and it makes tuning very difficult and finicky. This is the reason a lot of NA-T guys go with a standalone since there aren't any other great options (I think?).
On a TT it is easy and effective to convert the factory MAF system to MAF so you're good there.

On either version of the piggyback you'll have issues with OBD2 cars wanting to relearn over the fuel adjustments you've made, I dont think this makes any difference between a 1 or 2.

From what I'm told, if you're at 700 whp or below, there's no need to get into timing tuning, meaning that unless you want launch control, 2 maps, or any of the other features the 2 offers, then a 1 may be sufficient. That is what I based my decision off of.
