Welcome to the Campfire Coonass. You can (and should) spend DAYS reading old threads here about tents and stoves. Some very good knowledge has been shared already, and ultimately, it boils down to what YOU intend to use them for.
I own a Soulo, and think it's a superb winter tent. It would be too hot and lack the ventilation you'd want for LA in the warm months however. Tents rated as "four season" means they can handle snow loads and wind better than three season tents, but it doesn't necessarily mean they're perfect for all four seasons. There are many good three season tents on the market, and they'd probably suit your needs better unless you plan to hunt out west at higher elevations.
Here's a great video review of the Soulo, being tested where it can really shows its strengths and features.
SouloI don't own an MSR Reactor, but as a gear geek, I've been tempted. IF you're looking for the lightest and simplest stove, strongly consider these two.

For canister fuel stoves you've got lots of options. Same with liquid fuel.
Enjoy reading up on the old threads. You'll quickly learn there's no one right answer. You might also find yourself building a collection of gear for various conditions/scenarios.
