Why should the two characteristics be exclusive? The Ensenada20 is a starter boat; so is the Flying Scot. Both are tanklike and practically indestructible.
Indestructible is a good
quality in a starter boat. 'Starter boat' can mean 'forgiving, simple, inexpensive to own, gateway to larger boats and voyages.' Needn't connote 'badly made' or 'disposable.'
All Tanzers are tanks. The T22 weighs 2.5x as much as our SJ21. Tanzers were designed for the Great Lakes, where the chop is square and the storms come fierce. Their spars, rigging and hardware are larger than you would find on a comparable-sized Hunter or Catalina. They have medium to high ballast ratios. Yet for all that, they generally sail pretty well. You do need a good breeze to get em rolling.
The T26 is ... funky. Looks like the love child of a running shoe and a quanset hut.
Plenty of headroom tho, & I bet it tracks like a train. The lifeline stanchions seem dodgy (just a visual impression, not based on personal knowledge.) You might grab hold of a couple and see how solid they feel. A family friend has a T26 on Lake Ontario and loves it.
