They're both nice watches but completely different. I have the Gulfman and it's my favourite digital, I don't have the 1100, but it's a fine looking analogue. I think the real question here is, do you want analogue or digital?
To be honest, I'd pick either the GS-1100 or the GW-9100 over any G-Shock ana/digi. Both those models are very desirable. I understand what Mansrow means by 'best of both worlds', but in reality you tend to get the worst of the digital world on the ana/digis.
