We are a team that uses swerve as our default drive-train (all of our robots from 2010 through 2015 were swerve drive) and we love swerve drive.

That said, it's not suitable for all situations (we are not using swerve for Stronghold), whereas wheeled tank drive is. If you want a drive-train that you know you can use next year, focus on wheeled tank drive.

It also takes a lot of time and effort to get swerve working up to its full potential. This took us three years.

I would strongly recommend mastering wheeled tank drive before plunging into swerve. Swerve can be an awesome drive-train if it is executed well, but the advantage over tank is very game dependent. Poorly-executed swerve can be a disaster.
