Depends where you live and how you drive. Can't go wrong with Escort or V1. I like the GPS red light camera and speed camera capability of the Escort. I have had six Escort models over 25 years. One ticket on September 12, 2001. I would like to try the latest V1.
I owned three Passports and currently own three V1s. If you decide to go V1 call customer service and buy a refurb/return, they ship within a few days and look brand new for 10% off (or used to). Once you go arrows you never go back
I've been researching this for a couple of weeks. The consensus I have come away with is
Valentine for open Highway
Escort 9500 ix for city/ suburb
The idea is this. The escort learns to block the false signals and thus is more quiet around populated areas. Downside for Escort is that it is possible to miss a legit signal of a police radar who may be in close proximity to the known false signal.
The Valentine is not as sophisticated in blocking unwanted signals. The idea is that you should be cautious when any signal is present. However, Because of that, some may get tired of hearing the continuous signals pointed out by the Valentine or and therefore turn it off thus losing the use altogether.
On the open highway where there is not that many false signals from automatic doors, the Valentine's sensitivity and the arrows makes it a top notch detector. The arrows are a plus in helping to determine if the trooper is in front of you or sneaking up behind. It also tells you how many signals are there. The Escort doesn't give you this info
Neither is perfect. Both have their strengths and weaknesses. I would typically use one on road trips which leads me more towards the Valentine. But then the next day, I wonder if I really need those arrows and wonder if I should go with the Escort because it is quieter and would be less apt to get on my nerves in places like I-495 around DC.
Each has their proponents. But as one poster has said, you probably can't go wrong with either the Valentine or Escort
