TBH, my friend has a Pebble and I’ve often found myself preferring it over my Apple Watch. It accomplishes everything that is available, without fail. My Apple Watch, on the other hand, seems bloated with features, many of which take a ridiculous amount of time to load.
I had an original Pebble before my Apple Watch and my biggest complaint was that the BT would drop CONSTATNTLY... and when it did, it would make the phone cycle looking for it. I could use up 50% of a battery without trying if I didn't catch it. And it would of course not do all those smart functions.
I did like the charge, but honestly, I charge my phone nightly. My phone and watch chargers are directly across from each other - it takes an extra 3 seconds to plop the apple watch onto the 3 dollar dock I bought on Amazon that uses my Apple charger to get it geared up.
My one biggest problem with Apple Watch is third party apps - they just don't act like they should. The Apple official ones work nicely - the third party ones get gimmicky.
