I personally loved it when we implemented tapatalk originally as vb was terrible in mobile. Since moving to xenForo though I must admit having the full range of the available features that tapatalk just didn't provide is a breath of fresh air. The fact I can now be useful on the go and perform proper full featured moderation on mobile is superb.
Some things are still a little awkward but they tend to be things I'd normally do across multiple browser windows, so they aren't really awkward per se, just not as welcoming as my normal method of working on pc. These things would also be a pain on tapatalk but at least in a browser, even on mobile, I still have the option of multiple tabs to ease those tasks.
