They don't compare to the first (the one from 1994, which was great!). But all the others aren't memorable in my opinion. And they just get worse each time.
They're decent enough though, and if you're not familiar with the lucharesu scene picking them up will give you a decent idea of what is out there now. They're certainly worth the price, especially in comparison to WWE PPVs.
I have them.. 94, and 95 were the best.. They dont get worse each time.. J Cup is a special kinda puroresu.. It a cruiser tournament.. It is what got me into puroresu, and I look forward to them.
As long as you like high quality junior wrestling there is no reason at all not to get those two shows, even if you had to pay "top dollar" at Highspots, but since Bannabop (and many others) will sell you copies for less, buy it from whoever gives you the best price, and buy more puro with the money you save.
