Some of your wired cyclometers you have to turn on too. Modern GPS's don't take long at all to be ready to go. Only time they might take more than just turning them on is if you travel quite a distance away from where you last ended a ride and turned it off. Quite a distance being on the order of several thousand miles, but even then only a minute or so. Not the 10 or more minutes some very ancient GPS's use to take. But you do have to push a button to start it recording, so there is that. But it'll still give you the speed and some other stuff till without the timer being started until it automatically shuts off, unless you disable that.

My big thing for the GPS cyclometers is that I can see were I was on the map after a ride. And I can see my pertinent metrics at every log interval. 1 second for me. So very useful for training if you wish to get that into it.

Wired cyclometers are less expensive. But you have wires that interfere with cleaning the bike. Which is the nice thing about hydraulic and electronic shifting. It eliminates the brake and shift cables along the outside of the bike as hoses and wires lend themselves better for the bends encountered internally on many frames.

Cyclometers that are wireless for the sensors were at one time getting up toward the cost of a low end GPS cyclometer. Don't know where they stand now.

Trying to keep the manufacturing costs down to compete more favorably with the GPS cyclometers, the wired and wireless might have a lower MTBF. But that's just my speculation. And of course the lower end brands offering really inexpensive GPS cyclometers probably have a lower MTBF too.

It really doesn't matter to me what you use. Just use what you like, suits your purpose and is useful to you. Don't fault me if I don't find value in the things you like.
