I'm going to go ahead and pull out my usual line of "whatever looks good to you probably will be". Even the more distinctly below average shows have their qualities and their fans. If a premise or even something as minor as a suit appeals to you, I say go for it.

That being said, my go-to recommendations would probably be Agito or W/Double, though. The word that comes to mind to describe both of them is "solid", which makes them great introductory shows, not really being notably deficient in any areas. As for which out of the two you'd want, Agito is a little slower and more "slice of life", while Double is a lot more energetic and adventurous.

Blade is a show I think is great but I'm hesitant to recommend it given its slightly rough opening (at least that's the popular opinion), and the TV-Nihon subtitles are pretty dang bad, and I'm not sure if anyone has come along and done a better job yet.

Also, while I personally have major problems with a lot of Gaim, it's a really engaging show that's great at keeping the tension up and making you want to see the next episode. Pretty much built for marathon viewings.
