I used the Ameda Lactaline before. I think it's good. I like it compared to the Medela Mini Electric. I've not tried the other brand that you mentioned.
Ameda has variable suction power which you can control and it's pretty quiet. I liked it. I think if you buy it nowadays you can get the pumpin' pals handsfree strap to strap the bottles to breast so that your hands are free. But I've never figured out how to use it. Plus there're addtional components to wash if you wanna use hands-free.
You might also want to consider the Medela Free-style? My cousin is using it. It's hands free and the suction is good too.
I think Moms in Mind offers a trial for Ameda and Medela. You might want to check out their website to find out more.
