aby vs iva

I am holding ABY ATM.

For the last year or so ABY remained at around 40 cents and it has moved up in the last few days to 57 cents.

I am watching IVA for the same time. It had a very wild ride. Up and down (IVA was at around 80cents when ABY was 38cents etc).

Now I am thinking about switching from ABY to IVA.

Can a few of you enlighten and help me whether it will be a good switch?

Only one concern I had before was IVA's mine life was very short however IVA has got lots of interesting projects (ABY is constrained to only two and new projects are very small though very close to the existing ones).

I have a good idea about ABY but nothing much about IVA, can you please get me some good info so that in the coming days I can decide about switching?

thanks in advance guys for your help.
