I don't think the GPS has been removed, now I would say stainless Steel is not an upgrade over titanium, the 5 Pro is for people who live a rugged lifestyle like climbing etc.
I was at the unpacked event and spoke to various Samsung managers, the classic gets upgraded every 2 years and the pro gets upgraded every 2 years, so next year the 5 pro will be upgraded and in 2025 will see a new classic. Yes you can use the lte version without an esim like a normal Bluetooth version. I hope this helps, I am torn between keeping my 5 pro or upgrading to the 6 classic, both are great.
Well, I never had a classic, and the 5pro was my first Samsung watch, with all the discounts and offers I was able to get the 5pro for only £120 and now the 5classic for £180 so I will keep both for a while. The 5 pro is nice I get like easily 3-4 days out of one charge etc.
Went with BT again as I have read horror stories about LTE version battery and overheating issues even when LTE is off.
