3 years ago i'd say that sense was an awful interface for htc, when i was using the htc desire, but now i like it over touchwiz, unfortunately the htc hardware didn't cut it for me so i went with the s5. It's a great phone excluding the touchwiz UI, i'm intending on rooting it to a cyanogen modification when the warranty has gone.
hey, if the iphone 5s had android then i'd be all for buying that phone but unfortunately apple are cunts and have a very limited operating system on their phones, and jailbreaking it just makes it as unstable as stuff even after downloading one package from a trustable repo.
i wish all phone companies had one vision of sharing operating systems and not being so against each other, unfortunately that'll never happen cos companies want moneyz
