the problem i've got with the other brands that you've mentioned is the lack of protection in them. i ended up using the rdx gel products cos of the protection that's built into them -- i got too many soft tissue injuries using the other products.
you might have a different experience to me. i've also got a pair of Title 14oz boxing gloves that are really comfy but get mega sweaty though
i think the message should be shop around and make sure that you can try stuff out before buying if possible
