So, basically, you want to join the people at the ReDump Project - the goal of the project is exactly to dump again (hence ReDump) your old (vintage) retails discs in modern times and build database of vital details that allows everyone to verify his/her own dumps are correct - those details include Hash of the image, what protection is used, etc. Also, the ReDump database includes Barcode of the disc, which makes you determine, which one of several retail releases you own exactly and want to preserve.
Most important is that your image Hash matches the confirmed ReDump database Hash (CRC32/MD5/SHA1) - you can generate those hashes for the image using "HashCalc" application:
which is the most convenient one to use - otherwise there are countless apps that can be used to generates those hashes.
To make it more clear for you, what I am talking about, you can see for example here:
how ReDump database entry for "Monkey Island: Special Edition Collection" with Barcode of "0 23272 01111 6" looks like. So, if you own that disc and make yourself dump of it, what you need to check and make sure is that your image has SHA1 hash of "1eb7f1b3e72c7997afbe09e79f011688fd64f0ee" as per the ReDump database.
So, basically, you have 2 options:
1) time consuming and no any guarantees - hunt down and download of the Internet images of the discs you have, that are made and shared by other people, generate their Hash with "HashCalc" application and if they match the ReDump database keep that image as it's not piracy since you own the exact same disc that has that same Barcode and delete all other images for which you don't own disc with their Barcode (or even they are bad dumps as they don't match ReDump database hashes). Even if you dump your disc as far as the Barcode is the same, you will get exactly the same image with the exact same Hash, i.e. the same data. So, if the hash matches ReDump database you can be completely sure the data on the disc you own are the exact same as the image. Using this approach you're entirely on your own as ReDump doesn't deal with images in any way, because they consider that piracy as the image itself is copyrighted data.
2) do the dump yourself - depending on the protection used that could be very expensive, if you don't already own the necessary compatible drive. For example, if you need to backup CD disc protected with recent version of SecuROM you are more or less limited to Plextor PX-W5224 drive and on Ebay UK currently most cheaper offers for such drive are between 200 and 300 pounds!
More on the technical side - nowadays people use DiscImageCreator, not any of the tools you listed. Currently, DiscImageCreator is not full replacement for Alcohol 120%, but Alcohol 120% is used only in the few cases where DiscImageCreator cannot be used. You haven't mentioned any details about the discs you want to dump and preserve for yourself - if their type is CD, DVD, for what Platform they are (PC or other system), etc, but you can use this:

as starting point for compatible drives. If you have any further questions you can ask me, but I can not guarantee I know the answer. Once again, ReDump community and their forum is where the gurus on those topics are hanging out. Maybe, people here are members there as well and there is some overlap...
