Both of them are great firearms. It mainly boils down to personal preference, because they're very similar and the main difference between them are the Ruger has a thumb saftey, magazine disconnect, and chamber indicator. I would recommend you go to some local shops and compare the two, and if there's a range that has either one you can rent I would try that too.
