Depends on what you're wanting to use it for and the conditions it will be used in/dragged around in/etc.
The fenwick eagles are on the heavy side and aren't as sensitive as other ul rods. But they are well built & can take a lot of punishment.
The avid is nothing short of being driven around in a limo. Quality long casts with lite lures coupled with extreme sensitivity. St. Croix also has a panfish series of ul rods. The tips are faster than the avids and they beefed up the backbone making it a lot sturdier than most ul's out there. It's common to see people who buy the st. Croix ul's to pair them with shimano stadic's and nani-foil line.
FWIW:
I wanted to setup an ul rod this year targets panfish. After handling, reading, looking, asking about rods I ended up with a 7' ul uglystick. Not the best choice by any means, was a tossup between it and the fenwick eagle. I went with the uglystick simply because they are extremely hard to break & the ul's have an extremely strong backbone in them. Wanted the setup to fish ponds, lakes, rivers, break walls, with kayak's, waders, ride around in the back of a truck or jeep, used in wooded area's, etc. Pretty much get abused and keep on ticking. I'm running 1/64th oz to 1/8 oz jigs using 4# test and a diawa regal lt 2000. So far with that setup I've caught 200+ fish since april 3/4? including perch, bluegill, catfish, crappie, large mouth bass. The largest was the 19" catfish and the smallest was a 5" perch.
My advice:
If you are able to keep that ul rod out of harms way get a avid. If not get 1 that's good enough/strong enough to keep you in the game and pair it with good line & reel.
