bro, howz the camera? have you used it personally???
If you are asking about U11, then, I have never owned one but I was very very close for buying it, I had cash in my hand and 2 phones in front of me htc 10 and htc u11, I was literally shocked how beautiful htc u11 was and how powerful was the stereo on it such that I never heard anything close to it (considering it a phone) in my entire life, but still I went for htc u11 because I am a bit paranoid about glass phones.
Let me make this simple for you:
Htc U11 top notch everything, powerful chipset, stereo, very nice display, no headphone jack (i dont care) extremely fragile phone.
Nokia 7+ extremely nice display, no glass so a bit durable, beautiful stock android, less bezzels, weak chipset I have witnessed a slight lag which is not good for new phone.
OP5T used, a very good all rounder, very futureproof, very good battery and software, screen is not as good as nokia 7+ or htc u11 to my eyes.
These are my personal observation based on experience and not on paper specs. If I were you, in 50k, I would buy a new htc u11 or a used OP5T.
I am sleepy so ignore any mistakes.
