Quick Transmitter (telemetry) question

Hello,
I bought a Futaba 10J about a year ago. It's a nice receiver with quad modes.
Someone local told me telemetry was ok but a Spectrum Transmitter has better telemetry.
I didn't quite understand this. Any info/help about telemetry and transmitters?
Here is product page of my transmitter:

Hi you can get telemetry a few ways a display on the transmitter i have a DX9 which has voice so can tell me what i want to know as well as on the display with a quad reciver
If you do FPV you can have OSD so you will see display in your goggles
 
You need to keep display info to a minum or your be over loaded with data and trying to fly way to much
If racing just have battery power
If doing long range have battery , compass, altitude
 
Yah agree with both the responses here already in general keep the info to a minimum use buzzers or audible alarms for critical low voltage at least or if flying FPV OSD. If your receiver supports it and you want to use it having received signal strength indicator (RSSI) or link quality (different things).

Regarding one type of "telemetry" vs another, anything lumped under the label "telemetry" is really/literally just some data being collected one place then transmitted some other place. So all the radio communication really could be put under the broad label of "telemetry". What most people mean when they say "telemetry" with regard to TX/RX is the really the "signal strength" or "link quality" though.

RSSI and link quality I think are both somewhat subjective but from what I've heard on the YouTubes RSSI is really a thing that varies MFG to MFG and so the specific value your thing sends can't be relied on whereas I guess Link Quality is somewhat more standardized or includes more info about the specific link error rates/resent data etc. With any sort of network that isn't 100% there is retransmission so I think LQ somehow tracks this and determines how noisy the signal is vs shear amplitude that RSSI gives (keep in mind half guessing on all this :D )
 
Ultimately I just fly places I know I can recover my quad and if I'm flying somewhere it may be irrecoverable I make sure my signal is really good and edge out to check my "radio perimeter".
