R3000 vs R3880

Hi Guys

Would like some input if poss.

I own a R3000 which I think is fantastic !

I have had it about 9 months and although I don't use it a massive amount what it has done it has done superbly well

My (nice) dilemma is I have just won a 3880 ........:-)

Apart from size ....... is it any better than the 3000 ....or about the same?

For those who may have experience of both machines ......

Which would you keep and which would you move on?

In advance ...... thanks for any input
