Here is the comparison you asked for.
I did this because I also wanted to know the changes. Differences not yet announced and presented in the wiki and the news.
The new badges are not listed in this comparision, because a comparision of new badges with non-existing ones isn't possible ;-)
Cache Veterans get very young now, easier to get multi diamond level, but it's harder to get the "brainiac" D5 (tool / fishing caches) Badges.
Table is not presented in a readable way...
I'll append it as image:
Update 12. February - new changes:
I've updated my comparison of the level differences from old Badges and the newly changed on Februrary 12th.
Head in the ground (low altitude) now is easier and the diverse cacher needs 11 types instead of formerly 12.
If there were any other changes, please let me know.
I have not found any other.
