I use both, it depends what you want them for. A Solo-type stove with no fan (you can buy knock-offs on eBay for about $15) is light, super-compact, foolproof and unbreakable, but takes a bit of time to boil water while eating lots of twigs. If you're patient and need something light, it's great. The Biolite is a lot heavier and eats twigs faster, but boils a litre of water in about 6 to 8 minutes thanks to the forced-air fan (which goes like a blowtorch) and you can charge your GPS, emergency beacon, etc. I use a simple metal twig-burner for hiking, the Biolite when i'm kayaking and can carry more gear/weight plus need to charge gear on longer wilderness trips. Hope that helps.
