Glass cockpits make it a lot easier to assimilate information - that's the whole point of them. Traditional steam instruments demand more effort in training to achieve a good scan rate. It is therefore undoubtedly easier to transition from steam to glass than the other way around. I would advocate setting the higher standard in training to provide solid foundations of good technique. Then at a later date you can easily transition to glass. Do it the other way and you will make your life much harder.
1000hrs traditional, 2000+ hrs EFIS, in that order.
