PDE5 Inhibitors

Been using tadalafil but was wondering if anyone has any comparative feedback on other PDE5’s like avanafil, lodenafil, mirodenafil, sildenafil, vardenafil, udenafil, zaprinast, T-1032 made by Yanabe Seiyaku, benzamidenafil.

I’m looking for something that helps with carrying a fuller flaccid and overall help improving circulation in general. Any testimonies of any of these would be appreciated.
