I love Elton, but I’m going to throw a little shade at him right now over that comment.
I think it’s much easier to recreate Elton’s look with just about any actor. And many singing actors could probably sing like him too. I imagine it was much harder to recreate Freddie’s look and voice and get both right with just one person.
Oh Please. Elton's voice is nothing compared to Freddy's. Freddy's was once in a lifetime, who can compare? Even Adam only comes close, maybe some of the ladies for the range. Elton's talent is songwriting and showmanship, not voice.
Freddie had a 4 octave range. Rami can't really sing. He won't even do Karaoke. He said even if he could sing, he doubts he'd have Freddie's range. Plus, if you watch any videos with Brian May & Roger Taylor, they are very protective of Freddie, even today. And they try to incorporate him as much as they can whenever they perform. Like they showed an image of Freddie after their Oscar performance.
And when they had come out of retirement a few years ago, when Brian, who usually always did the song, "Love of My Life," alone with Freddie, without the rest of the band, sang it alone at Madison Square Garden. (Adam didn't sing it.) At the end, a holographic image of Freddie appeared. And Brian got all choked up. It was obvious he missed Freddie.
Brian & Roger wanted to incorporate Freddie's actual singing in the movie as much as possible.
Personally, I prefer to hear the real singer or band in a biopic about them. I mentioned this before in this thread: I remember watching Joaquin Phoenix & Reese Witherspoon in "Walk the Line." The movie about Johnny Cash & June Carter Cash. I was extremely disappointed to not hear the real singers. While I had heard Johnny in real life and Joaquin gave a good impression of it, I STILL have no idea what June Carter Cash sounds like
or how close Reese came to sounding like her. From what I had read, not much.
A little FYI about Freddie's range: For the song, Under Pressure, Rami said Freddie & David Bowie were long time, good friends. The two bumped into each other at Abbey Roads Studio (I think,) one day and that's when David said why don't they just jam and come up with a song together. While they were good friends, Freddie was still competitive, so he sang the highest notes he could sing for Under Pressure, to out-do David.
And we almost didn't have the song we have now. John Deacon, the bass player, came up with the famous bass guitar riff at the beginning of the song. But, they all went to lunch and when they came back, John, for the life of him, couldn't remember what he had come up with.
Freddie & David tried to sing it, but they had been too focused on creating the melody to remember it. Freddie was doing those "Mmm num ba de, Dum bum ba be," (which he used to do as vocal warm ups,) to have paid attention to what John was doing.) It also makes you wonder what they all were drinking or smoking during lunch that no one could remember.
Finally Roger, the drummer, was able to beat out the rhythm for John to remember the riff.
Otherwise, that song may have sounded way different.
And Vanilla Ice would have never become famous, after plagiarizing Under Pressure for "Ice, Ice, Baby."
so I figure I might as well watch the song playing in my head and switch up the videos of that song for variety. (Yesterday, it was "We Will Rock You," which was normal, as I had heard it the night before at the Oscars. But, also, "Radio Gaga, which I hadn't listened to in several days. 
) "We Are the Champions" is cut off in this vid, but I've seen videos where it is normally 7-8 minutes when they do the two songs and the audience really engages and sings along.
and These Were the Days of Our Lives. And of course Bohemian Rhapsody. And Somebody to Love. And I keep watching both The Great Pretender. Who, me? Obsessed?
Even when I don't know they are Queen songs they're in my head. I think a microchip has been implanted in my head that is fine tuned to a Queen radio frequency. 
Lady Gaga puts it to rest here at the 3:00 mark:
