My first warplane was the Pica FW190D. It is a dated design as far as construction goes, using hardwood mounts for the engine, and with a smallish tank compartment that doesn't fit much available on the market without some squishing and smashing. But, flying-wise, it is easy to fly, pretty fast and fairly predictable. I could never get mine to come down on approach, just kept floating unless you killed the power. I used a ST G61 and cjm retracts (which I wouldn't use again). I am sure that the Top Flite model of this plane would fly as well. If you are comfortable with a low wing plane, you shouldn't have trouble with either one. Mine flew a lot like a pattern plane that didn't have power enough to get it through a huge loop. I am sure that adding a .90 size engine to either plane would solve that problem. Be ready to build with either plane, they take a while, but the results are well worth it. I prefer building on the warplanes, as I feel they both look more scale, and fly less like a model and more like the real plane than the arfs. If you're looking for a 51, I have seen the Model Tech version fly, (it is an ARC) and it is very nice. Looks scale and flies the same, quick to put together. The one I saw had a YS 91 and it had LOTS of power, using mechanical retracts (reinforce the landing gear area). It looked great with my FW up in the air, he could fly circles around me.
