Seen all of these and love them
Seen the first 2 seasons
Haven't seen any, so can't comment.
Of the ones I've seen, I would suggest:
Now, let me preface by saying Dexter isn't my favorite show out of the 3, but it's the least commitment. LOST is my 2nd favorite show of all time, but it's a solid commitment. There's 20+ episodes a season all at around 40 minutes, and there's 6 seasons. It's a lot to get through. I think the payoff is much higher with LOST, but it takes a lot of time.
Dexter is more straightforward. There aren't nearly as many twists, turns, and questions in Dexter. Also, up to now there's really only been 1 season that would be considered subpar, while the rest range from good to absolutely outstanding.
I know it's sacrilege on this board, but I gave up on the Wire. I just found the pacing to be incredibly slow. I don't need explosions and car chases to keep me entertained, but the show just moves at a snail's pace.
Also, if you haven't seen Breaking Bad I would put that at the top. It gets better every season, and (along with Dexter) is still a "current" show so you can watch the final season live.
