I honestly prefer Never Say Die to TE, mostly on the basis of Junior's Eye's, and to a lesser extent the title track and Johnny Blade. Aside from Dirty Women there's nothing on TE that really grabs me, and that's mostly limited to seeing Iommi play it live.
Pretty sure I have a ticket to see the final tour somewhere, but since they went on sail a year before the show I've forgotten about it. I probably wouldn't have bothered, honestly, as I have a real beef with Sharon Osbourne's entire existence (God damned shame her father's dogs didn't get her, but at least he tried) and I'm pretty annoyed about the Bill Ward thing. But, tickets were reasonable and it's important to see Geezer and Iommi again before they croak. My preference would have been to buy scalper tickets so as not to support that filthy whore, but I wasn't in charge of the ticket procurement.
edit:
It's brighter than the sludge-fests that came later, and I absolutely consider Geezer to be one of my top three favorite lyricists.
Not sure what constitutes the sludgefest, although Born Again is certainly pretty dark. Personally, I consider the first few Tony Martin albums, TYR in particular, to be among the best they've done. Not on a par with SBS and Sabotage, but as good as or better than everything else.
