You need to look at know what type of fishing you are doing, eg. freshwater, saltwater, trout, bass, etc. You need to fit it to the rod you are using. Best for you, may not be best for someone else. Cost, features, etc. all have factors in it. Drag, bearings, line capacity are all things to consider. Consider too, how often are you going to use it. Will you be able to afford to buy another one when you grow appreciate a finer reel? Or will this be a one size fits all, and I had better buy the best I can, that I can afford now. Seeing that you are asking that which is the best spinning reel to buy, I am assuming that you are new to gear buying. Try something with modest cost from a known manufacturer, that will meet most of your needs. Save the rest for your next purchase. You can never have enough rods and reels, once you start matching gear to the fish you want to catch. Good luck.
