Both anime are made by the same studio, share the same director, character designer and audio guy, so you can probably see where i'm going with this.
The shows are very similar, the character deigns and colour palette are pretty much identical in each, both follow a group of girls in what is essentially a club like environment, and the comedy can be similar at times.
But, although the comedy is similar, the jokes land more often in Love Lab. WhereYuru Yuri grows stale after a couple of episodes of shallow characters telling the same recycled jokes, Love Lab has characters that are more interesting, funnier and more varied. If you enjoyed one, the chances are pretty high that the other will be up your street too.
Best friends Haruka and Yuu have just entered their first year at Misato West High School, a facility scheduled to be shut down in three years. The duo have been inseparable since middle school, but moving to a new school means making new friends. So together, the pair decides they’ll share something special that they won’t do with the other girls: they’ll share a passionate kiss. Now, the two, along with new companions Kotone, Shizuku, Kaede and Yuku, begin their high school days together, having plenty of fun - and sharing plenty of intimate kisses - along the way.
If you're a fan of cute schoolgirl comedies with lots of bright colours and a dash of yuri then these will most definitely be for you.
Well, i say "dash", and at least that applies for Yuru Yuri where the whole series just skirts around the issue with lots of implied inter-girl relations, whereas Sakura Trick storms out of the gates with full on tongue gymnastics from the get go. But fans of one will most likely find the other entertaining.
