I tried 490 half way and quit, mostly because I remember I had played it before. This one is not that fun, repetitive and the map is very big without details.
491 (XT17) Behind Enemy Line II (Haibo52313 Lin Yu Tain)
This one is awesome. Need a lot of strategy and trial error, with sniper at the top right difficult to get because of the edge (some glitch), so I had to try getting him from a different position.
Duke is the only commando, he need to play hide and seek and obtain bullets to take out five snipers that make his movement very limited (but not impossible).
The lack of resources is another challenge. Harvesting bullets from dead enemies is difficult, since it's hard to get, very limited, difficult to take down more than one enemy at one time, and have to continue running/hiding from the sniper.
It's extremely satisfying to take down the sniper and finish the mission. I love the freedom and ability to explore different strategy.

410. TY07 Sneak Attack Pearl Harbor (Tianya)
I remember liking Tianya's mission, the one without time limit, but those with time limit is too stressful and too impossible. There are too many things to do and will require me to try and try again by repeating the whole mission to get into the time, which becomes not fun. I only did it for the original Stop Bomb Deployment and succeeded, but the rush sucked most of the fun and it limits the way I can play it because of the time.
However, I decided to try again, and chose this mission. End result: I love but hate this mission.
Love: This is an awesome mission. It requires strategy and commando's collaboration. It gives me freedom to play. Lupin has to sneak around and supply ammunition for Duke, while he takes out those that is in his range since he can't cross the bridge without Lupin getting into the snipers that guard it (many!). Lupin plays hide and seek, and his expertise is really important here, fast and able to get in and out windows. This is awesome play! and very fun! But the cons ruin it.
Hate: Impossible timing. I probably needs at least 10 tries after knowing each step to take and will be pushing my luck to success. It wouldn't be fun anymore, especially because I can't find the second bomb to blow up the second tank. I had tried to position it in between, but by manual trigger it didn't work. If blowing up two tanks with only one bomb is the requirement here, I hate this because needing to be very precise, again, would suck out all the fun in trying. Again, limitation with only one way to get the mission going is not favorable.
Another 10 minutes/no time limit and the second bomb will make this mission awesome.
Screenshot: the time stops, and I continued to play. I got my bomb as the time stopped, and had cleared the square, bridge, and all snipers except the one in the two storey house (that apparently don't house anything important).
Can't finish as I couldn't blow up the second tank.
