I always heard the old reptile basic rhp had something that the snake could grab onto and hang out on it if it was determined, which a rhp is not a good thing for the snake to hang out on. I know they don't have that issue now, if the rumor was true in the first place. But that is where some bias could come from.
I think pro products looks better visually but I believe they both work fine as far as heating goes. Personally I use pro products in my carpet python cages. No issues
