Personally, if I could only choose between those two machines, I'd pick the Lenovo for it's better connectivity. I'd also sink the 80-Euro difference into a hardware enhancement. Being an AE guy, I'd go for more RAM right away.
You might be able to buy that machine with a bare minimum of memory, then get a whole lot more RAM -- 16 gigs is good to start -- from a third-party vendor, of equal or better quality and a lot less money. That's what I did when I got my HP Workstation a couple of years ago.
The ability to get more RAM would sway me towards the Lenovo. And the processor is just a touch faster too.
You asked for an honest opinion, so I would suggest that keep searching and get a quad core cpu with hyperthreading. Both the i5 cpus you mention above have only 50% of the cpu power of an i7 quad core with hyperthreading.
Most user, most applications simply cannot use a lot of cpu "cores" (physical + hyperthreads). Adobe however has written software that can use, or should I say require , lots of cores.
Street price of a cpu model would only be about 50 pounds more ($100 USD) for what I am suggesting.
Regarding RAM, I'd suggest getting at least 16GB with the expansion capability to go to 32GB. AE loves RAM!
Good luck with the search!
Definitely get a laptop that supports 32GB of ram. 16GB is really bare minimum at this point for AE CC 2014 for decent performance. Also JEShort is correct about the quad mobile with HT. You want those if all possible.
