Hi Mr,
Like you, my hands are small as well. I have both and there's a definite difference in the feel. The LV is wider and has a larger lever cap, which makes it feel even bigger than what it is. Comfortable in certain respects.
At about 1/4" wider it is very noticeable. But I'm not sure it is just a larger/smaller hand thing.
In the other thread several (myself too) also mention the LN bronze 102. Even smaller. For the Lee Valley version they call it their Apron Plane. Either of these smaller yet block planes are really versatile and down right handy to have.
As long as you'll be able to play around with each before buying, and depending on the work you do and how you envision using the block plane, the other thread also mentioned the LN Rabbet Block Plane. If you don't already have a good shoulder plane and you build using mortise and tenons, gives this a thought, too.
