I have a pair of Exide 135s rated at 226AH I got in 2011. They are still going, but starting to fade slightly on capacity. IMO your 2008s will be close to the end of life.
If you are off on a trip where it really matters IMO replace them ahead of time. If you are where the risk of them going out on you ( you are near a battery store) is low, keep nursing them until they just can't do the job anymore, then replace them,
I got a pair of Interstate GC2 XHDs at 232AH in 2011 too. (I use them as a bank of four) I can say they are fairly equal to the Exide 135s after six years. Both are good 6s. It would depend on price. In the States you can get the Interstate 232s at Sam's or Costco depending, for a real bargain price though.
