Hi, Gary,
Stick with what works. If it's doing what you need, then I'd say you're good to go.
For me, there are a lot restrictions on wood fires (generally banned due to high fire danger and dense population), so "chemical" stoves make a lot of sense. I also like not having to gather wood if I pull into camp late. Being able to fire right up even if everything around you is soaking wet is nice too.
