This paper provides amazing quality - you will not tell the difference between it and a photo printed in town (when using epson stylus photo r300) however there are a number of problems I have found.
1. Not waterproof - the smallest drop of water will smug the print.
2. The texture does not feel like a photo - didnt bother me but apparently makes a world of difference to my wife.
3. Expensive.
People said to get the best results you need to use epson paper on epson printers however I have just used Fujifilm multijet glossy paper and have been able to get even better results - and water resistant - and feels like a photo. But just as expensive.
