In case you missed it, Tower (https://www.git-tower.com – not affiliated) recently got a Windows version. It doesn't have the same level of quality as the Mac version yet (which I've been using for years) but it's improving rapidly and I expect it to be production ready within a couple of months. It's taking relatively long to port because thankfully it is made a native Windows application. Not free, but well worth the money.
Tobias here from the Tower team! I'd like to confirm your assumption: we're indeed working full-steam on improving Tower for Windows (and Mac, of course ;-)
We have quite some exciting features and additions on the roadmap!
