Similar or better then Sweet Tooth?

[fadeout]

So I have tried many various strains, and thus far my favorite that I have smoked would probably have been Sweet Tooth (though I also really liked Trainwreck, especially when I smoked a mix of that and Purple Haze and Sweet tooth, so dank)
What other strains are similar to Sweet Tooth or better? Also similar to Trainwreck or better?
