A little "kantei" game

[Laurian]

I’d like to make you a pre-Christmas weekend “game” proposition. 
Of course, this wouldn’t qualify to be any sort of kantei, not even close (as it’s based on pictures only), but I think it could prove useful to some of us who, like myself, are looking for advice and knowledgeable input from more experienced members. I confess, my goal is to open some constructive and enjoyable debate (if anyone is interested), but mainly to learn more from you guys. 
So, these are photos of two blades which, at least at first glance, seem to share many features, in terms of sugata, hamon, hada, etc. They are both suriage mumei, as you can see. Due to their similarities, I thought they’d make a good case for comparison. But of course, my untrained eye could have missed important differences between the two.
So, what do you think, attribution-wise?
For now, for the sake of this little game, I’ll only say that one of them is a Juyo Token, the other a TH. Can’t say which one is which. Maybe some of you have already come across these swords online, but, for the time being, I won’t be sharing any more information.
What do you think sets these blades apart? And what makes one of them Juyo material? Could the other one be a Juyo shinsa candidate as well, perhaps? I know, without the blades in hand, it’s very hard to tell, but still.
Thank you all!

If this is just silly, my apologies. Simply skip the post.

1st sword : Ko Mihara ?

 

2nd sword : Tegai ?

It is very difficult to say as I am often struggling to understand the fine differences. I would think these both are Yamato style swords and would be from late Kamakura - Nanbokuchō period.

 

For the first sword I would guess Tegai. My reasoning for that is that the 5 mainline Yamato seem to have their own small differences. To me Tegai would seem logical as for Taima I would expect tighter and "finer" jigane. Shikkake I would expect to see bit different hamon activity. Senjuin would have more "rougher" feeling to me personally and for Hoshō there would be so strong masame.

 

For the second sword I would guess Ko-Mihara. This one maybe does have bit tighter hada to my eye, however it does not seem like Taima level quality in overall as it seems bit weaker in presence than the first sword. My explanation of my thoughts might be difficult to grasp as it is difficult to put it in words. So I will go for Ko-Mihara on this. Honestly I could throw the same Tegai guess for this one too. 

 

I would not have guessed that either of these swords are Jūyō but if one is then I think it is the 1st sword.

Thank you! Very, very useful information. Respect, guys! 

The first blade was attributed to the Tegai school, while the second one to Hokke. Both are indeed Nanbokuchō.
