I have never yet seen a metal detector be released and be universally liked, it just doesn't happen.
The unhappy always shout the loudest, those that like a machine are usually too busy detecting and having a great time.
I've owned and trialled a lot of machines, nothing bettered my Deus 1
My mate bought an Equinox, and it impresses me, Minelab made a good job of that alright.
But there's no shortage of people advising others not to buy either of the above.
Still early days, lots of happy users, and XP never said the D2 would be a magic wand. Whether or not it's worth the upgrade is a very personal thing, but I'm confident it will be successful and drown out the moaners, like all good machines do.
