Best Epoxy Filler for Exterior work

Looking for a rec on a brand (or brands) of epoxy for repair and rebuilding rotted xterior trim. I’ve used a few different brands and I have yet to find one that I love. Painters and restoration guys, whats your favorite?

I've always been skeptical of epoxy fillers in wood. The materials don't match expansion very well.
I've had good luck with Minwax.
I've used WoodEpox from Abatron for 10 years and never had a problem. The stuff last forever in the bucket too so it goes a long way. It's a two part putty like product, easy to apply and sand when dry.
I've always used what the boat guys use- West system. Plenty of fillers available stocked at any marine chandlery.
