I always wanted to compare these two functions to see which won, and spoiler alert, it's system.tag.browse by more than an order of magnitude! At least for my very small site and test case...
sampling execution count = 50
system.tag.browse = 15ms
system.tag.query = 206ms
Code
provider = 'default'
query = {
"options": {
"includeUdtMembers": True,
"includeUdtDefinitions": False
},
"condition": {
"tagType": "UdtInstance",
"attributes": {
"values": [],
"requireAll": True
},

"op": "Or",

{
"op": "And",
"conditions": [
{
"prop": "typeId",
"comp": "Equal",
"value": "<Specific UDT Type>"

}
]
}
},

}
