Almost all Chanel "junkies" like myself, love both. You really can't go wrong with either one. Personally, I like the accessibility of a tote, because I am in and out of my bag all day long. My first purchase was the PST, and I am 5'7". I have a bad neck, so I don'tlike my bags too heavy and the GST is on the heavy side (then when you put all of your stuff in it....yah....you get the idea). But personally, I think both bags transition beautifully from day to night. Both are classic, and are sure to grab attention. At this point, I would strongly consider the function of each bag, and which will work better for you. I find totes to be more accessible...so that would be my vote for a first bag.
