I'm no expert, just an amatur but I really like the tenor size. I have a soprano, concert and tenor now and it really depends what you want to play, the Makala soprano sounds great for the price and the size is fun, the concert I have is really nice and probably my favourite uke but then the tenor works best if you are moving from a guitar background like I did due to the bigger size, you can play chords and solos down the neck a bit easier. If you can, try both sizes first, even if on a different uke so you know the size is right but the Kala Acacia has got good reviews and I like it, it has a good sound and build so you wont go wrong on either size. There are lots of reviews on line to help you. I have just put a low G string set on it and that seems to work well with the tenor size. Hope this is a little help.
