1 - Best toy acquisition overall
3 - Best pre-2014 toy(s) acquired
13 - Best non-toy item(s) acquired (like merchandise, DVDs, Comics, display items, etc)
Top 3 items come to mind (in random order):
#1 - Encore_Megatron (courtesy of member Zippo)
Last one of the Encore to complete the series for my collection. Been looking for over a year. Although the bot mode is flawed, this toy was the motivation to collect other series such as TF Collection, Commemorative series & Collectors Edition.

#2 - Transformers Legacy: Art of Transformers Packaging book
The only TF book I've ever bought & owned. FANTASTIC ILLUSTRATIONS. So much so that I ended up buying a replacement when the first book was defaced.

#3 - Botcon 2013(?) Rainmakers (Bitstream, Hotlink & Sunstorm)
The deluxe size is perfect. Fits nicely in the hand/ palm. But the colours really make these guys really pop.
