It's great, runs smoothly. I've had the 3 and 4 before and the flip series hasn't disappointed me yet. I think my only issue is with the navigation bar removing the 3 swipe gestures and replacing it with just one but that's more because of the new software update than the actual phone.
A beautiful phone to hold, at least the crafted black one; the hinge is very smooth; the crease is less apparent than before; perfect weight; but yeah, more could be done to use apps on the cover screen
The phone itself is nice but because it's more expensive than the flip 5 I traded in in my particular case I wish I had kept the 5. Yes the cameras are better and it has a faster processor, but the 5 was fast enough for me and the cameras were good enough. The AI is a parlor trick that I'll never use and gets in the way and I'm not getting much more battery time. About the only thing is the 7 years of updates, but I've had the zip 3, 4 and 5 and all of them required screen fixing after about a year so unless the 6 screen is a LOT stronger I'll be amazed if it lasts that long.
I am very satisfied with my new Samsung Galaxy Z Flip 6. I pre-ordered it and 512 GB of storage was included with the pre-order deal. I especially like the "flip" aspect which reduces the phone size-wise to 3+ inches, neatly fits in my pocket. That is the function I like most. The rest goes without saying - great Samsung quality in a solid Android phone which I believe are years ahead of that "other phone!"
