Danny Boy,
I have flown to most everywhere in Belize that both Maya and Tropic fly. Both have excellent pilots with good experience in short field airports. Maya has some older equipment but appears to be well kept and they are upgrading with newer. Tropic has most of the newer and larger planes. They work so closely together that I have flown on in country flights where the other air line carried my luggage. It was on the ground about the same time I was. Either are good, get to Belize soon and enjoy.
