For me the rb2 styling has been more influential over the design of roos that have followed, I love the colour scheme and I think it really is one of the truly classic LEs. I've never been attracted to the end of days as I am not keen on pvd finishes/blac...
Now if you had the RB1, it might require further thought but even then I feel the EOD would still edge it. Nothing like a bit of historical value when it comes to a watch and the EOD was the 1st of the LED ROOS.
However, the EOD was the first limited edition and does look quite nice too. However, choosing one, I'd keep the RB2. The 5070 is a super looking piece too. So another great choice too.
as recently i've been looking and both and been tempted by my dealer with some attractive deals. i'm still pondering. my heart tells me EoD but my head says RB2. my heart usually wins=-)
