My favorite Star Wars Lego set I own is my Duel on Naboo set. I love that it came with Obi-Wan, Qui-Gon, and Darth Maul.
I haven't bought much lego stuff in a long time. I did buy a Lego set that came with a Jango Fett though. I liked that one. The mini figure was awesome! I'm really looking forward to the Solo Legos. Those look great!
I've only got five sets so far, but it's close even amongst those! I think my 2015 Falcon just pulls ahead, but the BB-8 I just got for Christmas comes close too - I was a bit wary about it translating well enough into Lego, but it really is satisfyingly round to look at in real life and feels like quite a unique build process compared to my other sets. Still, the vehicles always seem the coolest to me as a rule.
I liked my Kylo Ren's command shuttle from The Force Awakens until it fell off it's shelf and is in 3 big pieces. After that is my Ahch-To training set. I end up buying a second one because it was 40% off. There is a new store chain called Dirt Cheap here in Houston (there are other stores in some Southern states) that sell a lot of stuff 40-80% off and I find a lot of year old Lego sets (Harry Potter, Ninjago and a lot of Lego Movie 2, besides others). I found Star Wars Lego from 2019 for 40-50% off. still spend over $150 each time I go there. Also, if you go late in the day the Lego sets are usually open and missing a few pieces to the whole box.
I would have to say the Duel on Naboo set released sometime between 2016 to 2017. Great little set, but it also goes from quite a lot these days so I'm glad I got my hands on it before it got too expensive.
So glad I still have this one. My favorite scene in the movies. I have several that are much bigger and more detailed, but I feel like the designers nailed the key aspects of this scene better than they have in any other set.
My Star Wars Lego sets are the following. Darth Vader helmet, Stormtrooper helmet, Scout Trooper helmet, Tie Fighter Pilot helmet, Luke Skywalker's Landspeeder, and A-Wing Starfighter.
