You will get a lot of different answers and eventually find out what works best for you. Unfortunately, the answer usually follows the purchase of several so so options first.
I have an Avet SDS and like it a lot. I would get the SDS if you are planning to ever use it for trolling. Like Kevin stated, it has great cranking power. I would assume any other quality 50 size reel would be similar. This size would be my first choice since I could use it for trolling, chunking, and AJs. I would spool it with 100 to 130 pound solid spectra and change topshots on it depending on how it is being fished.
If you want to use the reel mostly for chunking, I would consider a avet 30 narrow or similar reel by shimano or daiwa. This size would work great for chunking and AJs but may be a little small for trolling. I would spool it with 80-100 pound solid spectra unless I also want to use it for AJs (and it would work for this purpose). If also using for AJs, I would spool with 100-130 pound solid spectra. Many people like the hollow spectra to form loop to loop connections and because it is simplier on the hands.
I would also look into the new Penn Torque 300, trinidad 40, or saltiga 40/50 as an all purpose reel (all these options are high speed single speed). They aren't the best for chunking but will get the job done with a good rod unless you have pencil arms and a high voice. They aren't the best for trolling either. However, they should work great for topwaters, casting, and jigging.
For the big E, I have several set ups. You will need to compromise with one set up or limit your fishing options. I have 2 setups devoted to jigging, the SDS and tricked out TLD 20 devoted to chunking and AJs, and my toriums for casting.
