ultimate orbs

Usually in my ranked games whenever possible I try to get the ultimate orbs along the map, I had the opinion that it was always a good thing to do during the game.
However, as of lately I am starting to feel as though it's not always a great idea to stop and get the orbs for an x amount of time because of two reasons( which I think of), firstly because I'm noticing that I miss a lot of timings, such was when my team is executing or when I want to find timings to lurk. Secondly the noise cue it gives and although I never really been killed will getting a ult orb ( because I try to be very careful when using it) I have killed others or been notified of their location due to them using the ult orbs. Also whenever I am spectating someone or watching VCT or twitch streams, people don't really care about ult orbs.

What is your opinion on them? I am asking because I feel as though this is a underlooked feature of the game that people don't really think about( atleast in ranked).

ranked players rather get kills than win the game

You said it very well yourself
Ultimate orbs are a nice resource and objective you can get, but they are not free. They cost time and also sometimes cost your position. It's a balance between what and when you think is more valuable.

orbs don't feel as impactful as I thought they were at the beginning of the game, maybe since most ults have increased amount of points needed. I wouldn't hate some change to orbs to make them more impactful because csgo has 3 areas to fight for map control unlike valorant which has 1 before you get to site, I feel like fight for ult orb is what should/does make it different
