Spoiler for manga:

Roy is easily the best fighter in the manga because he is such a great tactician. It's not just about having the skills but how you use them.

As for not being good in close combat well Envy thought as much in Chapter 94 but Roy proved that he was just as good as close combat by pinpointing his attacks with one hand and making huge blasts with the other.

Does Roy's fire alchemy give him an advantage yes. But he definitely did not just get that advantage because of the alchemy

Now granted I did think Envy was not nearly as strong of a homunculus as some people assumed (since he relied quite a bit on manipulation than skill) but he did give Ed and Ling a hard time inside Gluttony.

Also as for the "no water" thing Roy even got around that in the Lust fight by using Havoc's lighter. Of course he might not always have this option but it shows that he was intelligent enough to come up with that plan and he is not just relying on luck and raw power.

edit: As for Wrath I do think he could give Roy a hard time because of his own skills. I am not so sure about Scar. In fact if it wasn't raining that one time they were about to fight I am not really sure who would have won. I think there is a good chance it would have been Roy. Well it all depends on who would have been faster.
