Like Joe said Tag doesn't get much respect from the watch collectors for the reason he describes.
And like Ian said the Tissot is much cleaner looking, I never used the chronograph feature (looks cool I must admit) or the rotating bezel, and the Tag was an quartz movement and the Tissot is a Swiss auto. Quartz is a little more accurate but the auto never needs a battery... besides if I want accurate I will wear my Casio G-shock.
This Tissot model was also once discontinued and now being put out for a limited time.
Thanks for your comments.
