Norse heathen reconstructionist here. There are a bunch I haven't heard of, but I'll try to write some lines on those I do and offer general opinion afterwards.
Buddhism: The incredible focus on right action is extremely endearing and a lot of buddhists are fine people. The rejection of the material world and its passions make little sense to me, and even gets a little odd in some extremes. For instance, the small-vessel path of letting a caste of monks liberate the rest of buddhists seems like asking for trouble.
Druidry: A kindred path. The druids follow the old ways and recognize the existence of vølvic journeying and the spirits and powers of the natural world. As good as it gets outside of my own ways, IMHO.
Hellenism: A fellow pagan reconstructionism, and very similar to norse faith. I know little about it, but wish I did.
Hinduism: Again, not an area of expertise, and it would appear that it covers as wide an area and array of gods as to be more a general term for all vedic-derived local faiths.
Jainism: Some of their tenets are what's really great about vedicism - Their compassion for animals and fellow humans is exemplary! I could do without the monasticism and creepy sexism, though.
Sikhism: Seems like cool guys, AFAIK they place a lot of weight on social justice, but apart from the cool turban and knife chic I don't really know anything else.
Wicca: Ah, wiccans, my frenemies. A lot of them hark to the old ways, worshipping the sky father and earth mother without preconceived notions. The fluff bunnies and their liberal christian sensibilities can bugger off, please.
Zoroastrianism: I only know that their god is really into fire, which is relatable but also worrying
