Just over $200 dollars...(HA HA)...
Seriously, probably not much but I don't know the manufacture of the York eyepieces. There is a reasonable chance that they come from the same/similar manufacture althought they may have different QC/QA specifications.
In general I would not recommend getting the "kits"...I'm not sure that the colored filters will get much regular use (some may disagree).
What eyepieces do you have now?
How do you find them?
The quality of the eyepieces in the two kits listed are likely to be very similar to the quality of the eyepieces that came with your scope..."Okay"
I'd recommend that you visit the Televue website and read up on the section and advice listed there about eyepiece selection. I found it to be a useful resource and learned a few things there myself.

One of the realizations that I came to as I got more viewing experience was that I tend to only use a couple of eyepieces on any given viewing night. A lower power "wide view" (magnification 35X - 45X), a medium power (magnification 90X-110X) and on nights were conditions permit a high power(magnification 150X plus). What eyepieces fit those categories will vary from scope to scope. Also do recognize that "my" definitions of H,M,L are just that..."my" definitions other people will use different ranges (and they will be correct for their scopes too).
Once I adopted the above as my philosophy I changed my way of acquiring eyepieces...instead of looking at "volume kits" for a few hundred dollars I begin to think about higher quality single eyepieces specific for my H,M,L power interests. I would then buy the best quality that I could afford.
For general "all around" viewing, in my opinion a Televue plossl is hard to beat. At Bintel a "new" TV 32mm plossl is $195, 20mm is $159, $15 is $139 (there are others too).
I would highly recommend that instead of starting with one of the kits listed that you pick 2 of the TV plossls instead. Your scope would determine which ones to pick (if you have a dob I'd get the 32 and probably the 15). There are some other "quality" eyepeices also available, Pentax among them but trying to compare plossls to plossls...the TVs will be "better" than the kit ones.
Also remember in the future if you decide to upgrade from the kits, the re-sale value will be almost zero (remember these are the eyepeices that get given away with new scopes)...With the TV you will already own a "top class" plossl but if you do want to sell it, you will get back a much larger percentage of the purchase cost. My experience has been that as I progressed to even more high end eyepiece designs (Pentax XW, TV Panoptics, Naglers etc.) I've still kept my TV plossls because on some objects and in some situations I prefer the view in them.
I know that the urge is strong to buy a whole bunch at once and in this respects the "kit" serves this purpose and looks to be a bargain...but it also will give you some bits that you will seldom used. I'd encourage you to redirect your eyes to a few "higher quality" eyepieces instead of a case full of "average" (not bad) ones...In the long term I reckon you'll get better overall value and use from buying individual eyepieces instead of the kit. Even if the budget only allows one. I get one of the TV plossls use it and save toward the next one.
Good Luck!
