I think reloading with giving 2 turns of no- advancing-no-attacking time to Hungary is the way to go and the "best gamewise" as it is fashion to be said lately
For me it is
1. "just reload"
2. "just reload with one turn no ground attack on Debrecen"
3. "just reload with less upgrades" (somewhere between 30 to 50 % of current upgrades) (hungaries proposal)
4. don't reload but no more city swapping
5. don't reload and keep on swapping
6. 2 turns of no- advancing-no-attacking
