LOOKING FOR CERTAIN STATS WEBSITES

I'm looking for a new website to use when looking at my stats. Preferably something that shows my record vs each champion as a certain champion. For example, it would show my record vs every support champion while I'm playing Janna. I don't know if something like this exists, but please help me if you know of such a site! Another website I was looking for is one that shows your record at each position so I can tell which position I excel at. I was using Attaqonline.com and Na.Soloq.gg, but now both stopped functioning. Also, if you just know of a really unique stats website please comment with the link! Thank you!!!!!
