Short answer: both are discontinued, and they are rated the same for sound quality (#18 and #17 of 73 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the Edifier T5s ranks #2 at $169.99.
What the Revel B8 does well: A discontinued compact sealed 8 inch subwoofer that adds upper bass support to a modest room. The tradeoff: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects.
Why pick the KEF T2: A discontinued slim sealed 10 inch subwoofer, under 18 cm deep, that slips behind furniture or against a wall. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects.
Buy the Revel B8 or the KEF T2, whichever you find used in better condition; both are discontinued. For a new speaker, start with the Edifier T5s instead.
