I think G&P is a good starting platform....I never had one brand new(mine I got it used), but I think you don't need to put money in to get it to work, barring getting more mags(which is is the fundamental issue with the WA system). Its essentially a propane ready version of the WA with upgraded steel internal and metal exterior. Mine was working when I had it, but I was set on getting NPAS with steel bolt carrier. There are some mod that I think you need to do to the gun which helps it a bit, one is to mod the bolt catch such that it has less chance of damaging your bolt. But other than that the platform is usable out of the box, at a significantly lower cost than Inokatsu, which AFAIK has a lot of problem in its earlier iterations. I can't say cost wise though how it compares to WE in Canada, WOC can get to US for as little as $550 USD, and while thats a lot higher than AGM, you are saving the hassle of having to replace the pot metal parts later....

Performance wise I don't know, WE shoots hotter as I understand, I think that comes down to the trade off WA system made to have a realistic field strip with a complete bolt, which is probably why a lot of people goes for WA in the first place(myself included), and I think as such there were more chances for bugs that need to be worked out....
