Microphone or headset? Help please

So, I really want a new mic or a headset and I have come down to the two best options for me: the Blue Spark Digital microphone and the Sennheiser PC360 headset. Now I just need help deciding between which one to get (if I get the PC360 I will also be getting the PCV 05 adapter with it for reasons which I will not state). Just to note: I currently have the sennheiser HD429 headphones. The headset and mic I wouldn't bring around, but If I get the headset I would bring my 429s around with me, while if I got the mic I would almost all the time leave my headphones at home. The microphone I can get for $180.15 while the headset with the adapter I can get for $181.55 (buying from amazon for both options). So I need your opinions because I seriously cannot decide. Also, my sound card on my computer has an output impedance of "<24 ohms", and the PC360s run at about 50 ohms, I believe, and I will not be buying a new sound card, sooooooo... Keep that in mind. Also note: I plan on using these for gaming and recording vocal audio of me gaming, and I will rarely use them for music.

I made a spreedsheet comparing the advantages and disadvantages between the PC360s and the Blue Spark Digital:

Thought it might help/modify people's opinions.

And I am not taking suggestions for other mics or headsets, I have found the two best options for me and I have spent many hours doing research, so stick to the topic of the blue spark digital and the sennheiser PC360s. THANKS!!!
