I like slicers but for pure great tomato flavor it is my opinion that many of the mid size salad tomatoes excel. My favorite used to be '4th of July'. Last year I tried several new varieties. My wife and I did a taste test and 'sweet cluster' won out over '4th of July'. Both plants are very productive and tomatoes are excellent. Very moist, great texture, full flavor and acid bite. The 'Sweet cluster' had just a hint of sweetness to round out that acid full flavored tomato. Sweet cluster tends to rival 'Juliet' for productivity, and IMO has a better flavor as that favorite as well. 'Juliet' is an oval salad tomato, a good bit smaller on average than 'sweet cluster'. Has a little less pronounced acidity, but great texture and flavor. Is excellent for drying as well as fresh eating. Is extremely disease resistant and a really productive workhorse. There is room for both of these tomatoes in my garden. For slicers, there are just too many that taste great for me to narrow it down. I love parks whopper, better boy, brandywine, celebrity, and some of the newer beefsteak varieties. I find it hard to be disappointed with these indeterminate large slicers. I don't care for varieties that are irregularly shaped and don't care for those with a big woody core. Aside from that, have not had a variety that disappointed me.
