There is no one brand that wins everything anymore.
Yes for a long time, the V1 did win everything in the performance arena but others are closing the gap and in some cases equaling or besting the V1 in one or two tests.
If you like the features the V1 has to offer, buy it.
If you like the features the Bel or Escort have to offer, buy it.
If you like the features the Whistler has to offer, buy it.
Let's not put others down for their choices as their needs may not be the same as our needs and their pockets may not be as deep as our pockets.
