I've been to the Pig's Ear twice, and loved it. Never been to Chophouse. So, I am curious as to what you are looking for and why you chose these 2. Might make the question easier to answer for those of us who may not have been to both.
I can't be hugely helpful to you, but seeing as you've not received any feedback yet I'll point out that The Chophouse is a food focussed pub (and therefore very relaxed in atmosphere) whereas The Pigs Ear is a restaurant. The food at both is well regarded.
