I moved from a Shoot' Chrony to a Labradar about 4 years ago. The Labradar is a big step up in convenience, for sure. I miss fewer shots with the Labradar, too. It does have its limitations, like sometimes not reliably reading small bullets and won't read much over 3900fps, but for most of my shooting, it works great. It is so easy to use that I pretty much always have it set up when target shooting. Works great for archery, too. Be aware that there are other doppler radar chronographs coming onto the market that may be worth looking at.
