If you could pick a SANS course to take which one would you pick?

It's been a quiet day at work so I've been listening to the CSA+ videos on Udemy and taking notes in between working on different tasks. My boss has been really supportive of my eagerness to develop my security skills. Today she stopped by and handed me a SANS Pen Test 2018 pamphlet and mentioned I may be interested in their training. I am incredibly, absolutely over the moon at her suggestion.
I'm going to take a good look at what courses are available and what aligns to my goals but I'm curious...
If your company paid for a SANS 4-6 day course which one would you take? Why? Would you recommend a different organization to take a similar course with? I'm familiar with SANS reputation. I just have a lot of questions swirling around in my mind right now.

But SEC503 and SEC505 looks interesting to me as personal choices as they would be more technical and think they would be more fun.
Currently Working On: Python, OSCP Prep
Next Up: OSCP

you will learn a lot about incident response, memory forensics, etc...stuff that are hard to learn elsewhere
I took three SANS courses before, and this stands out the most to me. For pentesting there are other training options other than SANS that have better money/value....GCIH is a bit too basic and you can read a book that has most of the topics...
What are your career goals?
When I was introduced to SANS I wanted to take SEC401, but the CISO strongly recommended SEC504 so I went in that direction. In my current role I decided to take SEC503 because we took over the NIDS plus I was interested in packet analysis after a few incidents. Now I'm leaning towards SEC560 after a redteam exercise we had earlier in the year.
SANS has so many offerings that I find interesting, but I do not have the time or money to take them all so I just focus on what's relevant to me at the moment.
I wasn't exactly looking for advice. This post was just out of mere curiosity
617 has no comparable wireless course offered anywhere else that I can find, and as I move more in to IoT, ICS, and less common protocols, the more I find in the wireless spectrum. Being able to quickly identify what's producing what is nice. Being able to work with that data more effectively would be a time saver. WiFi isn't an issue. BT aggravates me which means I need to learn more. For other protocols I can break out the hackRF and fumble through capturing data and replaying it, maybe modifying things, but I want to learn more.
