The first time I tried low g, I hated it. I did it because when I was in Hawaii, almost all the people I spoke with in uke shops and at factories said it was the way to go. But it didn't appeal to me, so I took it off. A few months later I tried it again, and it still didn't sound "right" to me. So I took it off again and went back to re-entrant tuning.
But then a few months later, I wanted to try my hand at "Europa" by Herb Ohta Jr. It was tabbed out for low g, so I tried it again. Turns out that was the charm. I now have crossed over to the "dark side" and there is no going back. I play the low g exclusively now. I still have two of my other ukes tuned re-entrant for strumming purposes, and I still think that older music ("Five Foot Two," etc.) sounds better with high g tuning. But 99.9% of the time, I'm playing the low g tuned tenor now. It is more range for fingerpicking music, and I think that rock and blues style music actually sound better with a low g tuned uke.
So give it some time. If it sounds foreign to your ears right now, that is because it is not the "uke" sound you probably are accustomed to. I think it is worth the effort of leaving it on for a few weeks to see if it grows on you. My first couple attempts I never left it on longer than a day or two. It turns out it took longer for me to get used to it, but now I wouldn't go back.
