   I use T-88 or West System Three. Mostly T-88 because you can get smaller quantities.

   I will say that it is really hard to get dried epoxy off if it gets where you dont want, unless you are prepared for it to run. I glued a table leg to a clamp once. Now use a lot of masking tape around the joints.

   I don't agree with the premise that epoxy will result in a stronger joint than yellow wood glue. The strength of a given joint is more a result of the design and fit of the joint rather than the glue used. A well fitted half lap joint, for instance, glued with yellow wood glue is stronger than the wood itself. Epoxy can't improve on that. Epoxy provides advantages in other ways, but not in typical well designed and fitted joinery.

   I avoid epoxy because, aside from the stick-everything-to-everything, it's brittle when cured, and it's not gap filling. Tight joints are more important than the glue used. One thing to try is cutting pieces of veneer to shim up the joints.

   Actually, epoxy is gap filling, that's its main advantage when the joinery is less than perfect.

   Actually, it is not. This is from a company rep who I called after a joint failure. I had glued some chair legs and rungs with sloppy joints using epoxy on the premise of gap filling ability. They failed. The rep said that ordinary epoxy is a glue and is not intended for filling gaps. They do make products with filler in them that work for that purpose. Or you can add filler yourself. I re-glued the chair joints using the same epoxy as before only this time I added fine sanding dust until the consistency was like peanut butter. A year later, the chair is holding up just fine with daily use.

   Epoxy is gap filling, unless you use the thin kind of course that is meant for laminating, there are just about all viscosities available. I adjust it with silica .

   I use yellow stuff when I don't have gaps. West slow cure when I do, but you have to combine it with a filler like silica to keeps it in the gaps without compromising strength.

   I'm with bilyo on this.
   If your joints need super strong glue, they need to be redesigned as failure is inevitable
