I didn't ignore Moo* as such. I looked into it (a long long time ago, though). I dimly remember it seemed to have a lot of performance and RAM usage problems, at least for my workloads. And it didn't bring enough benefits for my single-developer projects to make sense.
The asterisk is doing a lot of work there. Moose has always been and continues to be a beast (appropriately enough). That is to say it is big, slow and includes a ton of stuff I will never use - YMMV. OTOH, Moo is much smaller and leaner and I've had success using it without being too disappointed with the performance. However, for me (and this is very much an individual opinion) Class::Tiny hits the sweet spot of enough good stuff to be worth using with minimal (basically immeasurably small) overhead. Combine it with Role::Tiny and you have yourself a modern OO system that's bloat free.
Half the time I still just use bless and friends. Some of those times the model is standard enough that I should have gone with Class::Tiny from the start and other times the flexibility was a bonus. Horses for courses. But no mooses for me.
