Is it audit is better than sap fico

Dear gurus,

I am working with one of the big 4 in SAP implementation, but we were not having any project from last 1 year..frustrated with this, i decided to leave SAP ( I think now boom period is over and not much work left..)


Now when I have decided to leave this field and join System/IT audit , we got one SAP implementation project where I will be FI consultant.

can anyone please suggest me, that whether I should stay in SAP (my friends suggesting me to stay since there is good scope for this field) or shall I go for system/IT audit.
