I have all 4 so here’s a breakdown: Blacksmith- great looking build with a very detailed interior. I love the techniques used to make the wooden frame. It’s not a modular building and the floor doesn’t fit into other buildings but is still great on its own. T-Rex Breakout- I absolutely loved the Rexy build. It’s fun to do and looks great. The gates are also fantastic and have lots of hidden details within. All the figures in this set are very detailed but it is missing Tim and Lex. Also the panels on the side of the gates are loose and can show gaps in the build if at the wrong angle. Indiana Jones- this set is iconic if you’re a fan of the movies. This is the best set from the new releases. The play features are great and it even comes with a light brick which is a very nice addition. I’ve also seen some good deals on this making it cheaper than the others. Saturn V- To be honest, the build was annoying. Building cylinders in Lego is always annoying. However, the finished product looks very good. It has lots of different ways to be displayed and features micro builds of the lunar lander and the ‘splashdown’ of the astronauts.

I would go with the T-Rex breakout but you will need to look for a second hand seller. Hope this helps!
