Why not? It's still good for simple classification tasks. We use it as an encoder for a segmentation model in some cases. Most ResNet variants are much heavier.
Those slow and inaccurate models at the bottom of the graph are the VGG models. A resnet34 is faster and more accurate than any VGG model. And there are better options now -- for example resnet34d is as fast as resnet34, and more accurate. And then convnext is dramatically better still.
> ResNet > VGG: ResNet-50 is faster than VGG-16 and more accurate than VGG-19 (7.02 vs 9.0); ResNet-101 is about the same speed as VGG-19 but much more accurate than VGG-16 (6.21 vs 9.0).
