My experience is limited but I find shooting a garden variety AR10 to be easy and generally they seem to be quite accurate w/o a bunch of effort. Reliability outside of match tuned is unquestioned. They are heavy though. I dont find the M1A that comfortable to shoot and while they can be very impressively accurate they have a reputation of being finicky and prone to having some lesser degree of self degradation. AR10 has lotsa accessories available and can mout many sight or optics without a lot of hassle. Not as easy w/ M1A. Simple answer though is like you said, the M1A suits you so that is the way to go.
