Best Fitness Watch especially to use with cronometer

I would appreciate if you would like to share your experience with your fitness watch. I've read the reviews in the forum regarding problems with Apple syncing with cronometer, so my apple is out. I have a ten year old 305 Forerunner that I dug out of the garage (got me through LA marathon and a sprint tri....great at the time). Surprised that it has held up all these years and linked the heart monitor and I'll use these until I decide on a new watch. I want to stay with Garmin. I've read the new models will be out soon.

What are your experiences and recommendations! Thanks.
