The REST metadata for a service will tell you whether the service is cached or not. Look for the "Single Fused Map Cache" property.
If the service is cached (i.e. already has tiles), use the TileLayer. If it's not cached use MapImageLayer.
Example 1: https://sampleserver6.arcgisonline.com/arcgis/rest/services/MtBaldy_BaseMap/MapServer has "Single Fused Map Cache: true" -> so use TileLayer.
Example 2: https://sampleserver6.arcgisonline.com/arcgis/rest/services/911CallsHotspot/MapServer has "Single Fused Map Cache: false" -> so use MapImageLayer.
