I have used Boa laces on cycling shoes and ratchet straps. The Boa is newer and cooler. They claim equal pressure throughout the lace, hence it should perform better than other mechanisms. However I had issues figuring out how to use it...even after owning them for a long time. Hence I prefer simple ratchet straps.
Velcro can never get as tight as Boa or ratchet, so they must be inferior.
