Of course in terms of DR and ISO limit, the G2 lags behind. The question is how much affects these the quality of the pictures, and this comes down to the use cases. I still use a mighty GF1 (same era and specs as the G2), and I have no intention to replace it any time soon. But my use cases are snapshots of shorter trips / walks, family photos, and a few portraits (not many these days). And the results are mostly very satisfying, at least for me.
A few recent examples:
OOC with 'Natural' preset of the camera
OOC with 'Dynamic' preset of the camera
OOC with 'Natural' preset

'Natural' preset
Tweaked in LR, but as far as I remember from an OOC image

I only had the G1 before moving on to the GX7, but from memory I assume the G2 will share these same drawbacks...
Last year for some nostalgic fun, I decided to take the G1 out for the day. The form factor is wonderful and although 'only' 12mp, the images are super sharp and beautiful colours.
However I tend to shoot a lot of action and was quickly reminded of the shutter lag!!! ... It's certainly not the best action camera that's for sure.
It was a sunny day, so the ISO400 limit was not an issue, however the harsh light quickly revealed it's limited dynamo range.
I really loved using the camera and taking it out for the day was a good lesson. It rapidly brought to the fore my appreciation of what progress has been made and how fortunate we are to have the wonderful cameras that m43 now offers.
PS. Sadly the rubberised finish on the G1 had gone all sticky, however (and I know many will be horrified at this but) rubbing it in custard powder seems to have done the trick and made it feel nice in hand once more
.. No I don't recommend this method, the powder may well work it's way inside.
