Differences between the two Uno Ethernet shields?

Is there any substantive difference between the Ethernet 1 and Ethernet 2 shields? The Ethernet library gets updated, and I wonder if both shields are now about even in functionality. I know that one has a bunch of connectors on it, but I'm thinking about the networking aspects.

the Ethernet2 uses the W5500 chip which can handle 8 TCP connections at once. W5100 on Ethernet(1) shield can only 4

Thanks Juraj, but is that it? No difference in stability, throughput, extra processing on the ATMEL ucontroller, e.t.c.?

I know that I could review the W5x00 data sheets, but that wouldn't tell the whole tale as the chips' functionality has to work in tandem with the Arduino libraries. So I thought I'd ask here. Thing is, shield 2 is three times the cost of shield 1 on Amazon. Just for the header plugs?

there are clones of Ethernet shield with W5500 too. the expensive one is original Arduino
