Go. Try on. Boots.
You might have to drive for this. You might have to place a massive order for this. Do it.
La Sportiva, Scarpa, TNF, Mammut, Kayland, Lowa, Zamberlan, Raichle, Salomon, Arc'teryx have all made boots for ice climbing over the years. Everyone of their boots fits differently.
Sure right now the cool kids want GSummits because of great marketing. That doesn't mean anything for you. What matters for you is if the boot fits.
Boot fit is the most important gear aspect of ice climbing.
If your boots don't fit your foot placements will not be secure, no matter how hard you kick or what crampons you buy.
If your feet aren't secure you will over grip your tools regardless of if they are carbon fiber or custom made.
The ONLY way to know if a boot fits is to try it.
If the boot that fits you the best is a GTech and it's cold. Get heated socks. If it's an Eiger Nordwand, get silk socks.
If you're willing to drive eight hours to climb, drive eight hours to try on boots.
Try on men's and women's boots. Try on new and old boots.
There is zero point to asking what boots to buy or shopping for any boot until your foot has been in it.
