I like Peak candles. Super fast shipping, super nice people. They worked with me on wicks -- 100% beeswax takes larger wicks than recommended for blends. We went back and forth on sizes, materials, and cores, and they sent me stuff to try. I like their scents, their wicks, and their tech. Haven't tried Nature's Garden, but I do hear good things about them.
Good luck!
