Absolutely! From trust-minimized BTC bridging with BitVM to more scalable and private multisig with FROST and MuSig2, Taproot has given us some really great improvements.
Everything is good for Bitcoin in the context of learning and failing forward... perhaps the question then isn't optimally worded. Was it a failure or a triumph?
"It's bad but could have been worse and now we know should know better" is just a positive interpretation of failure.
I think that the activation was a failure, not as in fail to activate but the implementation - in Core - clearly had unintended side effects, so it was activated too soon.
For the feature itself, it's only a failure if someone other than me spends my p2tr coin due to a bug or cryptographic weakness, so that's too soon to tell. For example, if the quantum doomers are right and this turned out to be the last protocol enhancement, then it could become a failure in the future, but I'm not particularly worried about this right now.
There's been 0 benefit to Bitcoin's value prop as money.
All it has achieved is giving ethead adjacent/script kiddies a morale boost via precedent, such that they'll be able to continue pushing to make Bitcoin more like Ethereum. Incentives for development have completely shifted to pet-usecase centralized application stacks.
Abject disaster.
Nobody voting yes is actually keeping a meaningful amount of Bitcoin in a Taproot address, can all but guarantee they're bandwagon jumping hypocrites.

My hot wallet is, by utxo count, 97% taproot. My cold storage is 100% taproot but I did that much too early and should have waited for greater adoption and rolled over to a new p2wpkh setup instead.
I remember p2sh taking forever to get used too though, would you say that that was a disaster too?
Between you and @nout we've found the bulk of Taproot outputs....
Why do you use it? What's it doing it wasn't before?
The disaster is in the precedent it set, that useless forks can be astroturfed into activation... And now every shitcoiner that thinks Bitcoin should be an application stack is pushing for new ops
... Or even a material amount across all addresses total.
Proponents would seem to be either afraid of using it, or lied about their urgent use-cases all along.
On a purely relative basis, a proponents burden of proof is that they're no less "safe" than address types with a longer track record... But they won't put any skin in the game on their experiment.
Privacy is paradoxical, so I don't think anything should ever tout privacy as a feature or benefit, it should be incidental to something superior for its own reasons.
Things like Monero and Tor for example, privacy is the feature benefit, but that also makes them less private because it attracts a smaller anonset (retards) because they're otherwise useless, and more relative surveillance because it's a honeypot/target rich with said retards.
Privacy as a feature also leads users to stray from privacy practices due to a false sense of security. These undiscerning users fulfill the paradox of deanonymizing private systems through improper practices.
Taproot channels are often cited as a benefit to Lightning, but to your point nobody cares so use is negligible... and if we did get a flood of new privacy focused users, they'd quickly deanonymize an otherwise private network today through centralized swap services and ignorance of utxo management.
