“I have a few for saltwater, but I do go offshore for the GT popping trips in Vanuatu, PNG, Coral Sea etc. And I did pick most of them up second hand, but to me I guess it's worth it. I still drive a shitbox but that's where I choose to spend my money.
TBH, you can land a fish on almost anything, and I would go as far to say as you can land 80% of fish out there on any gear, but if I've travelled all the way with flights and boats and all that jazz I want to give myself the best possible chance to land the remaining 20%.
Lesson was learnt on my first ever Vanuatu trip I went with a sustain and a saragosa, thinking that that would be sufficient, but the sustain drag (fully locked down) could not stop many of the fish at all and the saragosa rotor shaft stopped moving the spool up and down to get the line lay after a 20kg coral trout (not even a big GT or Dogtooth tuna). And if you're out on a liveaboard there is nowhere to get it fixed or to get a new reel. So there's that. I do know many people personally who use these reels regularly with no issue, but I guess I've just developed a bit of a trust issue now.
Question is, do you want to lose a fish of a lifetime on a trip of a lifetime because of gear failure? But again, that's just me. Nobody really NEEDS a Stella, but I'm sure almost everyone secretly wants one.
Listening to Stella scream is something else. 
”Only thing I’d change about this post is after a bit more fishing experience I’d say 70% of fish can be caught with any gear, 10% will not be landed unless you have a winch and steel cable (I have a 6 year and counting feud with Dogtooth Tuna, and they’re still winning), and I’d like to think I’ve spent the money on giving myself a shot at the remaining 20%, if that makes sense.
Plus I agree with Dougie, if you’re casting large poppers or stickbaits at pelagics 8 hours or more a day, every gram does count, but you can’t trade off weight for quality either as feeling a reel seat flex under pressure fighting a fish is not fun, from personal experience.
