Eve is easier to land on, harder to take off from, they're both about the sameish level of difficulty to actually get to, from what I understand.
In other news, my 6 kerbal manned Jool mission is successfully orbiting Laythe!
The downside is that I massively underestimated the amount of fuel needed, and by the time I land the lander and SSTO (and hopefully... send them back back upto the mothership), I won't really have the fuel to get back to Kerbin infact i'll have about one standard mid size fuel tank worth left.
One part of the problem is just me not putting enough fuel in the design itself, the other part is that I didn't really fathom how much speed i'm aerobraking off in the Jool system, and therefore how much i'll need to put back on with thrust.
Lots of pretty pictures to come sooner or later
edit: for those wondering, laythe's gravity is 7.85 and pressure is .78.

In the end, it took me about 5-6 goes to land it. Firstly, I needed to actually have something to land on, so it took me a couple of goes to get my orbit right so that i'd end up on the tiny island that I did manage to land on. After that, I discovered that I couldn't really make an unpowered landing with the fully laden craft, 10m/s of vertical velocity downwards is way to much. After a few goes (reloading from the upper atmosphere) i managed to land it, twice actually, but i un-deployed my landing gear once i'd stopped the first time
As far as the chances of it getting back into orbit and rendezvousing with the mothership? i'd rate it highly, this craft on its own is able to get into Kerbin orbit, and this planet has 80% of the gravity and atmosphere.
Next up is testing the more traditional style lander.
