I have owned both the 95 (still own) and the 5400ES and found they are different but IMHO neither is substantially "better" than the other although I would give the 95 the edge. I kept the 95 as it plays everything.
I also owned the older XA-9000ES prior to the 5400 and felt the 5400 was better.
As to how they perform against a modded player only you can tell, as suggested order the 95 and return if it doesn't displace the TRL unit you have.
I owned a "Kerned" Sony 333ES over 10 years ago (I believe that it was the first 333ES that Richard worked on) so I can attest to the benefits (at least to me) of what mods can bring to the table. With that said IMHO I don't believe one gets the value of the mods out of the player when one goes to sell it so I don't know how much cash you would end up with in your pocket if that is your desired outcome...
