UBS-5 + Apparatus, ¿Vale La Pena?

[Enoch]

Is UBS-5 (2 versions ahead of USB port 3), worth buying?  How much better is it than 4?  Is the new textual apparatus much better than 4?  Is it $30 better than 4?

 

[incidentally, UBS-1 has the advantage of having in an appendix the alleged (& perhaps somewhat fanciful) allusions in the NT to the apocrypha.  -- perhaps as a freebie bonus, Accordance should add in that UBS-1 appendix.]

[Ιακοβ]

Apparently the changes are so minor its not worth the upgrade at all:
