Just as the title says, which was your favorite performance of each contestant?

For me I'd say:

Saara Aalto: No More Tears (Enough Is Enough)
Mat Terry: Writing's On The Wall
5 After Midnight: Signed, Sealed, Delivered I'm Yours
Emily Middlemas - Wings (Sing-Off Performance)
Honey G - Jump
Ryan Lawrie - Jailhouse Rock
Sam Lavery - Explosions (Audition Performance)
Four of Diamonds - Royals (Judge's Houses Performance)
Gifty Louise - This Girl (Judge's Houses Performance)
Relley C - Shackles (Praise You)
Freddy Parker - Love Is A Losing Game (Audition Performance)
Bratavio - Milkshake (Six Chair Challenge Performance)

My favourite performances from each contestant and the order I like them starting with the best:

Relley C - Shackles (Praise You) (Week 1)
Gifty Louise - Lay Me Down (Week 3)
Saara Aalto - My Heart Will Go On (Week 7)
Matt Terry - Writings on the Wall (Week 7)
Freddy Parker - Stay (Week 2 Results)
Emily Middlemas - Wings (Week 9 Results)
Four of Diamonds- Hold On (Week 5)
5 After Midnight - Stay Another Day (Week 9)
Ryan Lawrie - Jailhouse Rock (Week 7)
Sam Lavery - I'll Stand By You (Week 5)
Honey G - Jump (Week 5)
Bratavio - The Only Way is Up (Week 1 Results)

Saara Aalto- Who You Are (Sing Off)
Matt Terry- I Heard It Through The Grapevine
Five After Midnight- Motown Mashup (Week 2)
Emily Middlemas- What Makes You Beautiful
Honey G- Jump
Ryan Lawrie- Twist n Shout
Sam Lavery - Hello
Four Of Diamons - Royals
Gifty Louise - Lay Me Down
Relley C - Praise You
Freddy Parker - Love Is A Losing Game
Brattavio - Judges House? Idk.

Mine are virtually the same as this- except I would go for The Winner Takes It All for Saara.

I was struggling choosing one for Saara. Definitely between "It's Oh So Quiet", "No More Tears (Enough is Enough)" and "The Winner Takes It All". Even "Chandelier" could be a contender as her best or any of her sing-offs.

Sam Lavery - Hello (week 2)
Freddy Parker - Stay (week 2 sing-off)
Saara Aalto - It's Oh So Quiet (week 3)
Gifty Louise - Lay Me Down (week 3)
Relley C - Shackles (week 1)
Ryan Lawrie - Twist N Shout (week 5)
Honey G - Jump (week 5)
4OD - Hold On (week 5)
5AM - Get Ready/Reach Out I'll Be There (week 2)
Emily Middlemas - Human (week 8)
Matt Terry - You Don't Own Me (week 1)
Bratavio - Didn't do enough live shows

But yeah for me on average after the first 5 live shows I haven't found a new best for these acts besides Emily in my own opinion.

Saara Aalto - The Winner Takes it All
Mat Terry -Writing's On The Wall
5 After Midnight -Say You'll Be There
Emily Middlemas - It Must've Been Love
Honey G - Jump/MIB
Ryan Lawrie - Twist & Shout
Sam Lavery - Total Eclipse of the Heart
Four of Diamonds - Hold On
Gifty Louise - The sing off song (and her face after)
Relley C - Shackles (Praise You)
Freddy Parker - Killing Me Softly

Didn't see Bratavio at all so can't say. I didn't really enjoy any of Sam's, Ryan's or Gifty's performances but I feel Ryan did pull of some solid performances. I just didn't personally find them interesting.

As the OP didn't specify...

LEONA LEWIS - Summertime..

Nothing will ever beat that on this show!

Saara Aalto - It's Oh So Quiet or Chandelier (completely torn!)
5 After Midnight - Boogie Wonderland/September mash up
Matt Terry - I Heard It Through The Grapevine
Emily Middlemas - War Is Over
Honey G - Jump
Ryan Lawrie - Twist N Shout
Sam Lavery - Earth Song
Four Of Diamonds - Hold On
Gifty Louise - Lay Me down
Relley C - Shackles - HANDS DOWN THE BEST PERFORMANCE OF 2016
Freddy Parker - killing me softly
Bratavio none they were awful

BIB Couldn't agree more! Unbelievable that Relley has no real gig experience to speak of and she pulled that performance out of the bag on the very first live show too!!!

Saara: Chandelier (9)

5AM: Get Ready/Reach Out I'll Be There (2)

Matt: I Heard it Through the Grapevine (2)

Emily: Creep (4)

--- it's all same-ish bad so just pick the first one

Sam: Total Eclipse of the Heart (4)

4oD: Hold On (5)

Gifty: Rockin' Robin (2)

5am: Signed, Sealed, Delivered
Emily: Creep
Honey G: California Love
Ryan: Jailhouse Rock

As for the others I either can't remember or didn't like any of their performances.
