I've tried a couple like bikram yoga, green yoga, Sadhana Sanctuary, and also yoga taught by an instructor at botanic gardens. I'm currently on a hot journey with Hom yoga studio, review
here, it's pretty good so far! Personally i much prefer the smaller studios like hom yoga as the classes are more intimate and the instructors correct your postures more.
There are also quite a few guys taking up yoga recently- it helps in weight loss (hot yoga) and has helps in restoration/healing, good for sports people...
