I like them both, but prefer the Thai sparklie one. The other has a more Mahayana type look, imo, with the wider body. The sparklie one has the robes with one shoulder off, so appears to definitely be Theravada, but they are all symbols so the other is good too.
I would put the Thai looking one in a slightly safer place. Perhaps still on the tower, but on a small cloth, instead of books. But it is up to you, of course.
