Sapphire was my first pokémon game! So I'm quite biased towards Hoenn. I did like them genuinely, though. Also, just use repels! Problem solved.
Anyway, back to the remakes - I don't think it's likely, because Ruby and Sapphire were pretty complete games on their own, besides the lack of day and night. If there were to be a remake, I don't think it would be that great because there's not much to improve on.
Fire Red and Leaf Green added color and new islands to Kanto, and HeartGold and SoulSilver added more color and 3D-ness to Gold and Silver. As for Ruby and Sapphire, however, what would there be to add besides new places?
