Blood Lad
Gatchaman
Servant x Service
Silver Spoon
Uchoten Kazoku
...good ?
None of those shows are bad.
Blood Lad is probably the weakest of the lot, since it looks like it's going to go down a fairly generic shonen battle manga route, but it has a lot of energy and seems enjoyable to watch nonetheless.
Of those five, I'd pick out
Gatchaman Crowds and
Uchouten Kazoku as the most promising.
Gatchaman Crowds is a "sentai" (hero team) style show with tons of visual flair and energy and generally seems really nicely put together. The Gatchaman franchise is actually a really old one that started in the 70s, but this new installment seems to be very much doing its own thing and doesn't really require any knowledge of the old show.
Uchouten Kazoku, on the other hand, is a much more laid-back and quirky series with tons of atmosphere and nice characterisation, based around supernatural beings from Japanese folklore living their lives in modern Kyoto.
As for the other shows you mentioned,
Servant x Service is a fairly unexceptional but well-executed slice-of-life comedy. Its most notable feature is probably the office setting, which you don't see a lot in anime, so it feels pretty fresh. If you're interested in this series, I would also second other posters' recommendations of
Love Lab, which is the most enjoyable of the slice-of-life comedy series this season.
Silver Spoon, meanwhile, is a pretty down-to-earth take on farming life, with some comedy elements. It seems fairly engaging if you can get into the material, and a lot of people swear by the manga it's based on.
As for other recommendations...you might want to try
Watamote. It's not for everyone, but a lot of people here (myself included) are enjoying it a ton. And if you're open to anime that aren't currently airing, I'm sure people could come up with a multitude of recommendations for you (though you may want to give more indication of what types of series you're most interested in!)
