I have no idea if cheaper interconnect ends will be "as good". However, I started using low-mass BFA style bananas after I bought and used a pair of Nordost speaker cables with their Z-Plug version of the BFA style low-mass banana plugs. I think the most important factors for the BFA style banana plugs would be material type and connection type. I've typically soldered mine onto the speaker cables. However, there are also screw on (but they have more mass) and some have crimp tabs on them. I've used the crimp-on type, but I've always soldered them and just clipped off the crimp tab. Not confident in my crimping technique.
I've been very satisfied with soldered-on low-mass BFA style banana plugs.
