I have a vytec and love it. The menues are intuitive and easy to use uw. I´ve never had any dealings with their support (everything works) so I can´t comment on that. I don´t think you´ll run into any problems on repetitive dives if you dive "sensibly". I´ve done a few liveaboards with at least 3 dives/day without issues...
If by multiple tanks you mean that you´re thinking about techdiving, I´d say that most instuctors will propably want you to have a regular spg for those dives anyways so it propably wont be an issue either way.
Having said that I´m sure uwatecs are good as well. I have a uwatec BT and it does exactly what I want it to...
