Completely depends on how high your stats are already, but in most cases it makes sense to go for the lv10 upgrade. The only time I would not be upgrading a current LE during the event period is if the alternative is to upgrade a boost building or the comp factory - especially if your stats are not competitive. In my case, as all my boosts are lv10 today, I use the off cycle to upgrade the AMR.
Personally I think the ANI lv10 unit wasnt really worth my gold. As I said before, I reap the lv6-9 ANI units, they gave me a nice push in stats alone as well as a higher IPH. But the 10 crate events is always worth focusing more with your gold. Although the units aren't the best, the bonus they come with are... More bang for ya buck!
I made level ten ani upgrade using no gold with plenty o time to spare. Wambo, you still use defense buildings??

I have all the space in the world, land is at 190million, but it doesn't phase me. Plus all my defence buildings are looking after composite factory. This is a luxury that not all can afford.
There was time to get the building upgraded to level 10, though there wasn't much extra time built in. I made it, but I had to use a couple hundred gold bars on the last level. But that was because I had the money to upgrade my arctic oil rig to level 5 in the middle of the event and I chose to do that. Otherwise I would have completed in time. What we need is the ability to upgrade 2 buildings at once.
This must be Turkish Kabob street corner hut or somehting like that i hope
Was expecting the new building today, but no joy. Oh well, maybe tomorrow.
If there isn't gonna be a building can gree just let us know so were not sitting around waiting. I don't want to start an upgrade that's 60 hours long for the new building to come out the next day
