So does SourceTree. Have you tried using it? If so, what issues have you found with it? Personally, I don't use it, so I can't speak to its functionality.

I do the same in SourceTree, and find it trivial, but perhaps it's just a usage difference. If you want to use Tower go for it -- I have no affiliation with Atlassian to push the product on you, I just enjoy it. I'm just surprised at how much Tower costs.
I don't feel like $70 is very much for something that feeds my family. I use it all day every day and the work I do with it allows my wife to stay home with my kids. If people didn't pay me to build the software that _I_ build, this wouldn't be possible. It's the same reason I choose IntelliJ over Eclipse or other IDEs. If the price difference is justified by my effctiveness with your tool, I'm spending the money without hesitation.
The only caveat I have is, even if your product is the best, if your company is shifty or a bad actor- I'll do whatever I can to avoid it.
I branch and merge in moments at least a half dozen times a day in Tower. Getting to diffs, creating patches, and viewing changesets are easy and pleasant to look at. It has built I support for a Gitflow workflow so naming conventions and everything allow for one or two clicks to go from no feature branch to a new one.
Frankly, it's just pleasant to use, doesn't screw up my source, and makes it easy to get my code committed and pushed.
