The Shimano TL-FC32 might be OK for initial installation of external BB bearings, but can't be used with a torque wrench and will mark the bearing shells if used to forcibly remove seized external BB bearings. Which is only OK if you planned on scrapping them anyway. Otherwise I wouldn'tvwant to have to explain that to a customer.
The Shimano TL-FC33 is more expensive, and can be used with a torque wrench and won't mark the bearings - but its just the socket. Neither the torque wrench nor the socket wrench is included in the price. So the total price for the complete tool assembly will be a lot higher anyway.
The TL-FC32 is what I bought and for my home use is perfect. It was low cost ( but not "cheap"), strong and fit the cups very well. True it won't accept a torque wrench but that isn't a big deal for English bottom brackets.
If I were running a shop and going to install and replace external cups every day, i woiuld have gotten the FC33 or the Park BBT-19 but they would be an extravagance for my needs. however, I would think if the bearing cups had seized in the frame, you would be replacing them with new ones anyway so marking the old ones shouldn't be a problem.
Finally, a ratchet or breaker bar and torque wrench are required for so many other jobs in bike repair and I can't imagine any even modestly equipped mechanic not already having them so their not being included with the cup tool is a non-issue.
