The value of the two amps is probably similar since the BF amp has a non original cab.

Does the BF amp have the original blue caps and transformers?

Which amp sounds better to your ears and which amp do you prefer to play?

I would probably keep both amps, unless I wanted to sell off one amp, to help finance another gear purchase. Which is usually why I sell my gear and justify my next gear purchase.

I guess it comes down to your preference to which amp to sell.

Wish you good luck with your decision and potential sale.
