Sealstone events are very easy to get 5*s in (not counting random completion rewards) if you're below lv80. You don't need to spend items at all for the 5*s plus a mag or two but SW is good for sealstone if you're busy and don't have too much time to hunt bots.

Sealstone events tend to be harder for lv81+, which is probably why your guildmates said it's bad :) if you have DNs/rems, save them for a future tower when you're higher-leveled. Tower is only good if you have a lot of HP :) you'll want to prepare reducers and low-cost daemons to clear the WGs though.

Towers have many more 5*s than the 200F (which lately -has- been a CQ daemon, granted) that are useful for much more than CQ! So yes it's worth using items on if you have the time :)
