Haha - well you did post this in the LV forum I do love a good balenciaga and with the strap it's a bit more versatile if you are only considering the handheld version of the speedy. The speedy is never going anywhere though. It's a classic.
I love this comment as we are definitely biased here, being LV loversThis forum is biased so we are more likely going to endorse our beloved speedy. I have many other designer bags but no Bal bags. I once considered one and an SA at Barney's BH said he did not feel the quality was commensurate with the price- it is def a trophy bag but I think there are better choices and of course LV is right up there. GL with whatever you decide!
